icon上添加数字提醒

使用viewbadger包:

package com.jingle.vierbagerstudy;

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

import com.readystatesoftware.viewbadger.BadgeView;

public class MainActivity extends Activity {

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

        initImg();
    }

    private void initImg() {
        ImageView img = (ImageView) findViewById(R.id.img);
        img.setImageResource(R.drawable.ic_launcher);
        
        //使用image,context初始化badgeView
        BadgeView badge = new BadgeView(this, img);
        badge.setText("ok");//设置显示的数字
        badge.show();//显示badge
　　　　　　//badge.hide()//隐藏badge

    }
}
