安卓。爪哇。如何以编程方式更改应用程序图标及其名称？

  • 772

我注意到标准的android日历具有以下功能：每天，根据月份中的哪一天，图标都会发生变化。也就是说，如果今天是第 1 天，则图标将显示数字 1，如果是第 31 天，则分别显示数字 31。

问题：如何自己实现？问题 2：是否可以通过编程方式更改应用程序名称？如果是，如何实施？

java

    添加权限

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

    我们添加两个方法：

    private void shortcutAdd(String name, int number) {
// Intent to be send, when shortcut is pressed by user ("launched")
Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
shortcutIntent.setAction(Constants.ACTION_PLAY);

// Create bitmap with number in it -> very default. You probably want to give it a more stylish look
Bitmap bitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
Paint paint = new Paint();
paint.setColor(0xFF808080); // gray
paint.setTextAlign(Paint.Align.CENTER);
paint.setTextSize(50);
new Canvas(bitmap).drawText(""+number, 50, 50, paint);
((ImageView) findViewById(R.id.icon)).setImageBitmap(bitmap);

// Decorate the shortcut
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bitmap);

// Inform launcher to create shortcut
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(addIntent);
}



private void shortcutDel(String name) {
// Intent to be send, when shortcut is pressed by user ("launched")
Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
shortcutIntent.setAction(Constants.ACTION_PLAY);

// Decorate the shortcut
Intent delIntent = new Intent();
delIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
delIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);

// Inform launcher to remove shortcut
delIntent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(delIntent);
}

    最后我们挂起听众

    @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.test);
findViewById(R.id.add).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        shortcutAdd("changeIt!", count);
    }
});
findViewById(R.id.increment).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        shortcutDel("changeIt!");
        count++;
        shortcutAdd("changeIt!", count);
    }
});
}

    原始答案在这里
