我正在使用此代码：

public void Close() {

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

switch(which) {

case DialogInterface.BUTTON_POSITIVE:

dialog.dismiss();

MainActivity.this.finish();

break;

case DialogInterface.BUTTON_NEGATIVE:

dialog.cancel();

break;

}

}

};

final AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setMessage("Thanks");

builder.setPositiveButton("Quit", dialogClickListener);

builder.setNegativeButton("Stay", dialogClickListener);

MainActivity.this.runOnUiThread(new Runnable() {

public void run() {

builder.show();

}

});

}

当用户选择退出时调用Close() . 它会打开一个警告框“构建器” . 当我在构建器上选择“退出”时，出现此错误：

MainActivity.java的第42行引用builder.show() .

在选择“退出”按钮时，我执行dialog.dismiss()，然后执行Activity.finish() . 我仍然得到窗户泄漏 .

为什么即使在dialog.dismiss()上也会出现此错误 .
