在我的应用程序有时我收到此错误：

 java.lang.IllegalArgumentException: Receiver not registered: android.widget.ViewFlipper$1@4806a4a8

这是什么？我该怎么办？需要一些帮助,请…

这是一些代码：

on onCreate()方法我有这个：

vf = (ViewFlipper) findViewById(R.id.details);
        vf.setFlipInterval(3000);
        vf.startFlipping();
        populate();

其中populate方法是这样的：

private void populate() {
        for (int i = 0; i < jArray.length(); i++) {
            System.out.println("lungime" + jArray.length());
            LinearLayout l = new LinearLayout(this);
            l.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                    LayoutParams.FILL_PARENT));
            l.setBackgroundColor(0x000000);
            l.setOrientation(LinearLayout.VERTICAL);
            vf.addView(l);

            File f = new File(Environment.getExternalStorageDirectory()
                    + "/Downloads/");

            File[] files = f.listFiles();

            Bitmap bitmap = BitmapFactory.decodeFile(files[i].getPath());
            img = new ImageView(this);
            img.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                    LayoutParams.FILL_PARENT));

            img.setImageBitmap(bitmap);

            System.out.println("target " + target[i]);
            img.setOnTouchListener(this);
            img.setId(i);

            l.addView(img);
            img = null;

        }

解决方法:

根据Daniel Lew’s solution,创建这个类：

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ViewFlipper;

public class GabrielleViewFlipper extends ViewFlipper {
    public GabrielleViewFlipper(Context context) {
        super(context);
    }
    public GabrielleViewFlipper(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    @Override
    protected void onDetachedFromWindow() {
        try {
            super.onDetachedFromWindow();
        }
        catch (IllegalArgumentException e) {
            stopFlipping();
        }
    }
}

并且在你的布局中不使用普通的ViewFlipper,使用GabrielleViewFlipper：

<your.package.GabrielleViewFlipper
    .
    .
    .
</your.package.GabrielleViewFlipper>
