我正在调用相机意图并处理onActivityResult（）中的位图。我正在通过NDK处理图像，工作正常。然后我想打开一个对话框来呈现图像，但没有任何反应。

现在我发现在其他机器上（不在我的机器上）会抛出错误：
MainActivity has leaked window that was originally added here
我觉得onCreate（）方法的代码有时会取消对话框吗？虽然只启动了UI内容和一些后端通信
UPDATE ：在另一个deivce上运行应用程序时，tid 12737（RenderThread）中的致命信号11（SIGSEGV），代码1，故障地址0x24（更快，SGS6而不是SGS $）。对话框显示，单击其中一个图像视图时出现此错误

尝试在OnActivityResult中设置您需要显示对话框的标记，并在onResume中检查该标记，然后在OnActivityResult而不是<tr><td><a ng-href="#">Call us</a>
<span class="glyphicon glyphicon-phone" > </span>
</td>
中创建对话框。
有关为什么在活动生命周期方法中提交片段事务（在本例中显示对话框）不是一个坏主意的更多信息可以找到here。
答案 1 :(得分：0)
如果您要在MainActivity中显示对话框，则可以检查MainActivity位于前台的标记。
可以这样：
boolean isActivityResumed = true;
@Override
protected void onResume() {
// TODO Auto-generated method stub
// When activity is in focus, it will be on resumed.
super.onResume();
isActivityResumed = true;
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
// When activity is out of focus, it will be on paused.
super.onPause();
isActivityResumed = false;
}
然后，在显示对话框时检查此标志：
if (isActivityResumed && dialog != null) {
dialog.show();
}
答案 2 :(得分：0)
尝试按如下方式创建对话框：
final Dialog dialog = new Dialog(context);
dialog.setTitle("Only select properly segmented pictures:");
dialog.setContentView(R.layout.dialog_segmen);
Button dialogButtonRetry= (Button) dialog.findViewById(R.id.dialogButtonRetry);
dialogButtonRetry.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dispatchTakePictureIntent();
}
});
Button dialogButtonDone= (Button) dialog.findViewById(R.id.dialogButtonDone);
dialogButtonDone.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
获取ivWahetLeft
ImageView ivWahetLeft = (ImageView) dialog.findViewById(R.id.ivWahetLeft);
