public class MainActivity extends Activity {

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

        TextView tvAddress = (TextView) findViewById(R.id.tvAddress);

        Geocoder geocoder = new Geocoder(this);
        List<Address> addresses = null;
        double lat = 22.6721740;
        double lon = 120.3100350;
        try {
            addresses = geocoder.getFromLocation(lat, lon, 1); //放入座標
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (addresses != null && addresses.size() > 0) {
            Address address = addresses.get(0);
            String addressText = String.format("%s-%s%s%s%s",
                    address.getCountryName(), //國家
                    address.getAdminArea(), //城市
                    address.getLocality(), //區
                    address.getThoroughfare(), //路
                    address.getSubThoroughfare() //巷號
            );

            tvAddress.setText(addressText);
        }

Android MVP 設計模式 Spinner練習

練習MVP設計模式，以Spinner為例
將檔案切成Model View Presenter

1.在Layout放置一個Spinner元件
2.View - MainActivity.java

package com.terryyamg.mvptest;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

//View
public class MainActivity extends Activity implements MainActivityView {

    private Spinner spinner;
    private ArrayAdapter<String> listAdapter;

    private MainActivityPresenter presenter;

    @Override
    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'
}

2.AndroidManifest.xml

3.res/layout/activity_main.xml

4.MainActivity.java

package com.terryyamg.shortcutbadgertext;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import me.leolin.shortcutbadger.ShortcutBadger;

public class MainActivity extends Activity {

    private int badgeCount;
    private EditText numInput;

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

        numInput = (EditText) findViewById(R.id.numInput);

        Button button = (Button) findViewById(R.id.btnSetBadge);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                badgeCount = 0;
                try {
                    badgeCount = Integer.parseInt(numInput.getText().toString());
                } catch (NumberFormatException e) {
                    Toast.makeText(MainActivity.this, "錯誤:", Toast.LENGTH_SHORT).show();
                }

                ShortcutBadger.with(MainActivity.this).count(badgeCount); //次數

                Toast.makeText(MainActivity.this, "通知次數=" + badgeCount, Toast.LENGTH_SHORT).show();
            }
        });


        //find the home launcher Package
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
        String currentHomePackage = resolveInfo.activityInfo.packageName;

        TextView textViewHomePackage = (TextView) findViewById(R.id.textViewHomePackage);
        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();
    }
}

iOS Swift Multiple PickerView Spinner 多重 關聯 連動 滾輪

2017.06.18 update Android的下拉選項為Spinner
相對應的iOS的為滾輪PickerView

1.首先在Main.storyboard拖拉一個Picker View元件

並點選右方Show the Connections inspector
將dataSource與delegate拉致上方圖片上三個小圖的最左邊小圖關聯

2.將storyboard元件拉至ViewController

3.ViewController繼承UIPickerViewDelegate, UIPickerViewDataSource

iOS Swift 筆記 暫存 SharedPreferences StandardUserDefaults

Android的筆記暫存功能為SharedPreferences
iOS相同的功能為NSUserDefaults.standardUserDefaults()

        //儲存在記事本
        let preferencesSave = NSUserDefaults.standardUserDefaults()
        
        preferencesSave.setValue("張三豐", forKey: "name") //儲存字串
        preferencesSave.setBool(true, forKey: "boy") //儲存布林值
        preferencesSave.setDouble(178.5, forKey: "height") //儲存Double
        preferencesSave.setInteger(99, forKey: "year") //儲存int
        //儲存
        let didSave = preferencesSave.synchronize()


        //讀取記事本
        let preferencesRead = NSUserDefaults.standardUserDefaults()
        
        if preferencesRead.objectForKey("name") == nil {
                //  Doesn't exist
                NSLog("NO name", "...")       
        } else {
                let name = preferencesRead.stringForKey("name") //讀取字串
                let boy = preferencesRead.boolForKey("boy") //讀取布林值
                let height = preferencesRead.doubleForKey("height") //讀取Double
                let year = preferencesRead.integerForKey("year") //讀取int
                NSLog("name:\(name!)", "")
