Question

是的，我看过一大堆教程，问题等，但没有一个有效，所以我不需要更多链接，我只需要修复我当前的代码..

到目前为止，我有这个：

public class FullscreenActivity extends Activity {



protected int[] mThumbIds;

@SuppressWarnings("unused")
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fullscreen);

    // get intent data
    Intent i = getIntent();

    // Selected image id
    final int position = i.getExtras().getInt("id");
    ImageAdapter imageAdapter = new ImageAdapter(this);

    ImageView imageView = (ImageView) findViewById(R.id.full_image_view);
    Button SetWallpaper = (Button)findViewById(R.id.setwallpaper);
    imageView.setImageResource(imageAdapter.mThumbIds[position]);

}
        private Object[] imageIDs;
        private int position;


        public void onClick(View arg0) {

        try {
            WallpaperManager.getInstance(this).setResource((Integer) imageIDs[position]);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        }
     }

但是当我选择了图片后单击按钮时，它什么也没做？

我也有清单中的许可，但它仍然无效，所以任何帮助都会非常感激

谢谢

我不确定这与它有什么关系，但我在三星Galaxy S4上测试应用程序
