实际上，我在应用程序“ ActivityManager中的ANR keyDispatchingTimedOut”中收到以下崩溃报告。生成的logCat如下所示。谁能告诉我错误的确切位置。我尝试了很多，但无法再次再现该错误。它发生一次，在那之后它没有显示，尽管我没有做任何事情来纠正错误。

最佳答案
您可以将您的方法实现为
onStart方法
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
doLongerTask();
}
需要很长时间才能完成的方法
private void doLongerTask() {
final ProgressDialog dialog = ProgressDialog.show(Client.this, "Please wait", "Doing long task...", true);
dialog.setCancelable(true);
//dialog = CustomProgressDialog.show(this, "", "");
new Thread() {
@Override
public void run() {
try{
//TODO Write here your method logic
sleep(5000);
} catch (Exception e) {
Log.i("your_app_tag", e.toString());
dialog.dismiss();
}
//Dismiss dialog, and notify handler to done this task
dialog.dismiss();
longTaskHandler.sendEmptyMessage(0);
}
}.start();
}
完成长时间的处理后将处理UI更改的处理程序。
private Handler longTaskHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch(msg.what) {
case 0:
//Here you can implement UI code. like if you are using listview
//then you can refresh listview.
break;
}
}
};
这不仅是一种方式。阅读here了解所有可能的方法。
快乐的编码:)
