Question

在android 4.2我的应用程序工作正常，但当我尝试使用android 4.0.4测试它时，我有此消息错误：

我使用setBackgroud添加一些动画，比如这段代码

AnimationDrawable animation = new AnimationDrawable();
                                 animation.addFrame(getResources().getDrawable(R.drawable.d1), 200);
                                 animation.addFrame(getResources().getDrawable(R.drawable.dio), 1000);
                                 animation.addFrame(getResources().getDrawable(R.drawable.da1), 200);
 animation.setOneShot(true);
 view.setBackground(animation);
 view.post(new Starter(animation));

我已将支持库添加到我的项目中，我不知道如何解决这个问题，任何帮助都会被贬低！

Answer 1

已添加到API 16，尝试setBackgroundDrawable()

Answer 2

除了@dmon回答：你可以用这种方式调用正确的方法：

if (Build.VERSION.SDK_INT >= 16) {

    layout.setBackground(animation);

} else {

    layout.setBackgroundDrawable(animation);
}

Answer 3

试试这个，它对我有用：

＆＃13;

Bitmap bitmap = BitmapFactory.decodeFile(new ImageLoader().fullPath + "/desiredFilename.png");
Resources res = getResources();
BitmapDrawable bitmapDrawable = new BitmapDrawable(res, bitmap);
int sdk = android.os.Build.VERSION.SDK_INT;
if (sdk < android.os.Build.VERSION_CODES.JELLY_BEAN)
   ll.setBackgroundDrawable(bitmapDrawable);
else 
   ll.setBackground(bitmapDrawable);

＆＃13;

Answer 4

这是我的问题：

imageButton.setOnTouchListener(popupWindow.createDragToOpenListener(imageButton));

我像这样修复它：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    imageButton.setOnTouchListener(popupWindow.createDragToOpenListener(imageButton));
                }

当我使用android.widget.RelativeLayout.setBackground时，NoSuchMethodError
