獲取可繪製圖像ID

Question

我在可繪製文件夾中有許多圖像。我想將當前選定的圖像作爲牆紙按鈕單擊。

int[] resources = { 
    R.drawable.tssr_1, 
    R.drawable.tssr_2, 
    R.drawable.tssr_3, 
    R.drawable.tssr_4, 
    R.drawable.tssr_5, 
    R.drawable.tssr_6 
}; 

WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext()); 

try { 
    //set wallpaper picture from resource here 
    myWallpaperManager.setResource(R.drawable.tssr_1); 
    //showToast("Success set as wallpaper"); 
} catch (IOException e) { 
    //showToast("Error set as wallpaper"); 
} 

這裏R.drawable.tssr_1被硬編碼，以便應用程序成功地設置tssr_1圖像作爲牆紙圖像。我想設置當前顯示在屏幕上的圖像。我如何獲得該圖像的ID？

Answer 1

ViewFlipper vf = new ViewFlipper(getApplicationContext());   
    ImageView image = new ImageView(getApplicationContext()); 
    // set resId as image's tag, then add to viewflipper. 
    image.setTag(imageResId); 
    vf.addView(image); 

    // the listener will be invoked when image in flipper is clicked and held, 
    // then you can set the image as your wall paper. 
    vf.setOnLongClickListener(new OnLongClickListener() { 
     @Override 
     public boolean onLongClick(View v) { 
      int resId = (Integer) v.getTag(); // get image tag 
      myWallpaperManager.setResource(resId); 
      return false; 
     } 
    });
