当前回答

解决方案是在退出Activity之前在view .java:183中创建的对话框上调用dismiss()，例如在onPause()中。所有的窗口和对话框应该在离开一个活动之前关闭。

其他回答

  if (mActivity != null && !mActivity.isFinishing() && mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }

不仅尝试显示警报，而且当您完成一个特定的活动实例并尝试启动新的活动/服务或尝试停止它时，还可以调用它。

例子:

OldActivity instance;

    oncreate() {
       instance=this;
    }
    instance.finish();
    instance.startActivity(new Intent(ACTION_MAIN).setClass(instance, NewActivity.class));

最好的解决方案是在try catch中添加对话框，并在异常发生时解散对话框

只需使用下面的代码

 try {
        dialog.show();
    } catch (Exception e) {
        dialog.dismiss();
    }

当activity销毁时解散对话框

@Override
protected void onDestroy()
{
    super.onDestroy();
    if (pDialog!=null && pDialog.isShowing()){
        pDialog.dismiss();
    }
}

最好的解决方案是把它放在显示progressbar或progressDialog之前

if (getApplicationContext().getWindow().getDecorView().isShown()) {

  //Show Your Progress Dialog

}
