android.view.WindowLeaked 窗体溢出

android.view.WindowLeaked一般会发生在Activity 与Dialog的显示。 Activity 中create 一个Dialog，若你先关闭Dialog再关闭Activity就是正常的，若你先关闭Activity再关闭Dialog就会报错这个 android.view.WindowLeaked错误了。我分析这个原因是：Dialog是基于Activity而创建的：new ProgressDialog(this)；this 就是Activity。 Activtity先finish,那Dialog就没得依附了，所以就会报android.view.WindowLeaked。
例如代码： MAIN:

new Thread(){

@Override

public void run() {

// TODO Auto-generated method stub

super.run();

bufferingAppearHandler.sendEmptyMessage(0);

startNowPlaying();

bufferingDisAppearHandler.sendEmptyMessage(0);

finish();

}

}.start();

InitDataThread it = new InitDataThread();

it.start();

}

private void startNowPlaying() {

// TODO Auto-generated method stub

NowPlayingActivity.createPlayStationMusic(bundle.getString("stationId"), this);

Intent intent = new Intent();

intent.setClass(this, NowPlayingActivity.class);

startActivity(intent);

}

protected ProgressDialog bufferingDialog;

protected Handler bufferingDisAppearHandler = new Handler() {

public void handleMessage(Message msg) {

if (bufferingDialog != null) {

bufferingDialog.dismiss();

bufferingDialog = null;

}

}

};

protected Handler bufferingAppearHandler = new Handler() {

public void handleMessage(Message msg) {

bufferingDialog = ProgressDialog.show(ReStartActivity.this, "",

"Recovering", true, false);

}

};

}

当我在startNowPlaying();中finish Activity时候有时候就会报week linked错我。

Dialog是依存与一个特定Activity的。所以不能在其后dismiss。
