Android のデフォルトの壁紙トリミング オプションを使用して壁紙を設定する壁紙アプリを作成しています。

つまり、アプリで壁紙の設定ボタンをクリックすると、壁紙オプションをトリミングするように求められます。

デフォルトの組み込みの壁紙トリミングオプションを呼び出したいことに注意してください。Androidのデフォルトの画像ギャラリーアプリから壁紙を設定するのと同じように

スクリーンショットを参照してください:

これはデフォルトの壁紙アプリのスクリーンショットです。これを呼び出して、アプリの壁紙を設定したいと思います

ここに画像の説明を入力

これは私が試したものですこのコードは壁紙を直接設定します/画像の中心

// set wallpaper on button click
        Button b1 = (Button) findViewById(R.id.wll);
        b1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v2) {
                // // TODO Auto-generated method stub

                WallpaperManager myWallpaperManager = WallpaperManager
                        .getInstance(getApplicationContext());
                try {
                    myWallpaperManager
                            .setResource(MainActivity.ICONS[curruntPosition]);
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }

組み込みのクロップ機能を実装しました。これがそのコードです。

doCrop(); を呼び出すだけです。ボタンをクリックして、他に必要なものがあれば教えてください。

Button b1 = (Button) findViewById(R.id.wll);
    b1.setOnClickListener(new View.OnClickListener() {
