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();
    }
}
