Android RecyclerView

替代ListView方案 RecyclerView

1.在build.gradle(Module:app)添加compile 'com.android.support:recyclerview-v7:+'

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
    defaultConfig {
        applicationId "com.terryyamg.recyclerviewtest"
        minSdkVersion 17
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.android.support:recyclerview-v7:+'
}

2./res/layout/activity_main.xml

3.新增項目的layout /res/layout/item.xml
點擊效果
android:clickable="true"
android:background="?android:attr/selectableItemBackground"

4.新增分隔線class檔案 DividerItemDecoration.java

package com.terryyamg.recyclerviewtest;

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Rect;
import android.graphics.drawable.Drawable;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;

public class DividerItemDecoration extends RecyclerView.ItemDecoration {

    private static final int[] ATTRS = new int[]{
            android.R.attr.listDivider
    };

    public static final int HORIZONTAL_LIST = LinearLayoutManager.HORIZONTAL;

    public static final int VERTICAL_LIST = LinearLayoutManager.VERTICAL;

    private Drawable mDivider;

    private int mOrientation;

    public DividerItemDecoration(Context context, int orientation) {
        final TypedArray a = context.obtainStyledAttributes(ATTRS);
        mDivider = a.getDrawable(0);
        a.recycle();
        setOrientation(orientation);
    }

    public void setOrientation(int orientation) {
        if (orientation != HORIZONTAL_LIST && orientation != VERTICAL_LIST) {
            throw new IllegalArgumentException("invalid orientation");
        }
        mOrientation = orientation;
    }

    @Override
    public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
        if (mOrientation == VERTICAL_LIST) {
            drawVertical(c, parent);
        } else {
            drawHorizontal(c, parent);
        }
    }

    public void drawVertical(Canvas c, RecyclerView parent) {
        final int left = parent.getPaddingLeft();
        final int right = parent.getWidth() - parent.getPaddingRight();

        final int childCount = parent.getChildCount();
        for (int i = 0; i < childCount; i++) {
            final View child = parent.getChildAt(i);
            final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child
                    .getLayoutParams();
            final int top = child.getBottom() + params.bottomMargin;
            final int bottom = top + mDivider.getIntrinsicHeight();
            mDivider.setBounds(left, top, right, bottom);
            mDivider.draw(c);
        }
    }

    public void drawHorizontal(Canvas c, RecyclerView parent) {
        final int top = parent.getPaddingTop();
        final int bottom = parent.getHeight() - parent.getPaddingBottom();

        final int childCount = parent.getChildCount();
        for (int i = 0; i < childCount; i++) {
            final View child = parent.getChildAt(i);
            final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child
                    .getLayoutParams();
            final int left = child.getRight() + params.rightMargin;
            final int right = left + mDivider.getIntrinsicHeight();
            mDivider.setBounds(left, top, right, bottom);
            mDivider.draw(c);
        }
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        if (mOrientation == VERTICAL_LIST) {
            outRect.set(0, 0, 0, mDivider.getIntrinsicHeight());
        } else {
            outRect.set(0, 0, mDivider.getIntrinsicWidth(), 0);
        }
    }
}

5.新增點擊class檔案 RecyclerTouchListener.java

package com.terryyamg.recyclerviewtest;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

    private GestureDetector gestureDetector;
    private ClickListener clickListener;

    public interface ClickListener {
        void onClick(View view, int position);

        void onLongClick(View view, int position);
    }

    public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
        this.clickListener = clickListener;
        gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
                if (child != null && clickListener != null) {
                    clickListener.onLongClick(child, recyclerView.getChildAdapterPosition(child));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

        View child = rv.findChildViewUnder(e.getX(), e.getY());
        if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
            clickListener.onClick(child, rv.getChildAdapterPosition(child));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

6.主檔 MainActivity.java

package com.terryyamg.recyclerviewtest;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private String[] ss = {"no.01", "no.02", "no.03","no.04", "no.05", "no.06","no.07", "no.08", "no.09","no.10", "no.11", "no.12"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RecyclerView rv = (RecyclerView) findViewById(R.id.rv);
        MyAdapter adapter = new MyAdapter(ss);
        LinearLayoutManager lm = new LinearLayoutManager(this);
        rv.setLayoutManager(lm);
        rv.setHasFixedSize(true); //當RecyclerView大小沒改變時最佳化
        rv.setItemAnimator(new DefaultItemAnimator()); //預設動畫效果
        rv.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL)); //分隔線
        rv.setAdapter(adapter);
        //監聽事件
        rv.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), rv, new RecyclerTouchListener.ClickListener() {
            @Override
            public void onClick(View view, int position) {
                Toast.makeText(MainActivity.this, ss[position],Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLongClick(View view, int position) {

            }
        }));
    }

    public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {

        private String[] ss;

        public class MyViewHolder extends RecyclerView.ViewHolder {
            public TextView tv;

            public MyViewHolder(View view) {
                super(view);
                tv = (TextView) view.findViewById(R.id.tv);
            }
        }

        public MyAdapter(String[] ss) {
            this.ss = ss;
        }

        @Override
        public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            //設定item layout
            View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item, parent, false);

            return new MyViewHolder(itemView);
        }

        @Override
        public void onBindViewHolder(MyViewHolder holder, int position) {
            //放入資料
            holder.tv.setText(ss[position]);
        }

        @Override
        public int getItemCount() {
            //取得長度
            return ss.length;
        }
    }

Android Splash Screen 新開啟畫面

前篇開啟app啟動畫面
http://terryyamg.blogspot.tw/2014/06/android-splashscreen.html
另一種方法

1.在 res/drawable/新增launch_screen.xml 上方加入android:opacity="opaque" 中間放入logo圖片並置中

2.在 res/values/styles.xml 新增一個AppTheme.Launcher

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.Launcher">
        <item name="android:windowBackground">@drawable/launch_screen</item>
    </style>

</resources>

3.在AndroidManifest.xml加入 android:theme="@style/AppTheme.Launcher"

4.最後MainActivity.java

package com.terryyamg.launchscreenstest;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setTheme(R.style.AppTheme); //加入此行
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinner = (Spinner) findViewById(R.id.spinner);

        presenter = new MainActivityPresenterImpl(this);
        presenter.guide(); //導向
    }

    //Override MainActivityView 設定Adapter
    @Override
    public void setAdapter(String[] data) {
        listAdapter = new ArrayAdapter<>(this,
                android.R.layout.simple_spinner_item, data);
        listAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    }

    //Override MainActivityView 設定Spinner動作
    @Override
    public void setSpinner(final String[] data) {
        spinner.setAdapter(listAdapter);
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                                       int pos1, long arg3) {
                Toast.makeText(MainActivity.this, data[pos1], Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {

            }
        });
    }
}

3.View - MainActivityView.java

package com.terryyamg.mvptest;

public interface MainActivityView {

    void setAdapter(String[] data);

    void setSpinner(String[] data);

}

4.Presenter - MainActivityPresenter.java

package com.terryyamg.mvptest;

public interface MainActivityPresenter {

    void guide();

}

5.Presenter - MainActivityPresenterImpl.java

package com.terryyamg.mvptest;

//Presenter
public class MainActivityPresenterImpl implements MainActivityPresenter {

    private MainActivityView mView;
    private MainActivityModel mModel;

    public MainActivityPresenterImpl(MainActivityView mView) {
        this.mView = mView;
        this.mModel = new MainActivityModelImpl();
    }


    @Override
    public void guide() {
        mModel.setData(mView); //導向Model
    }
}

6.Model - MainActivityModel.java

package com.terryyamg.mvptest;

public interface MainActivityModel {

    void setData(MainActivityView view);

}

7.Model - MainActivityModelImpl.java

package com.terryyamg.mvptest;

//Model
public class MainActivityModelImpl implements MainActivityModel {

    @Override
    public void setData(MainActivityView view) {
        String[] data = {"A", "B", "C", "D", "E"};

        //放入資訊
        view.setAdapter(data);
        view.setSpinner(data);
    }
}

完成後就可以得到一個與一般的spinner相同的效果

Android Badger Icon 提示 通知 數字

icon上的數字提示通知，Android沒有內建的，所以使用第三方套件ShortcutBadger

使用IDE: Android Studio
1.建立新方案後，在build.gradle(Module:app)檔案裡的dependencies位置裡面加上 compile 'me.leolin:ShortcutBadger:1.1.3@aar' 下載該套件

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'me.leolin:ShortcutBadger:1.1.3@aar'
}

        textViewHomePackage.setText("手機型號:" + currentHomePackage);
    }

    @Override
    protected void onStart() {
        super.onStart();
        ShortcutBadger.with(this).remove(); //歸0
        Toast.makeText(this, "已讀", Toast.LENGTH_SHORT).show();
    }
