Android 安卓：如何等待点击警报对话框？

我准备了一个带有“是/否”按钮的警报对话框的异步任务。我需要返回1表示是，返回0表示否。 我不完全理解这个任务。要增加单击的等待时间，需要做什么？当前状态不等待

我不明白你的问题。但通常异步任务看起来是这样的。在这里，我添加了回调接口以返回结果。如果你有时间试试这个。请

public class AsyncGet extends AsyncTask<Void, Void, String> {

public interface AsyncGetResponse {
    void processFinish(String result);
}

private AsyncGetResponse asyncGetResponse = null;

public AsyncGet(AsyncGetResponse asyncGetResponse) {
    this.asyncGetResponse = asyncGetResponse;
}

@Override
protected void onPreExecute() {
    super.onPreExecute();

    // show progress dialog. If you need
}

@Override
protected String doInBackground(Void... voids) {

    String result = null;

    // do your background work here. Like API calls.

    return result;
}

@Override
protected void onProgressUpdate(Void... values) {
    super.onProgressUpdate(values);

    // update progress percentage. If you need.
}

@Override
protected void onPostExecute(String result) {
    super.onPostExecute(result);

    // hide progress dialog. If showing.

    // pass result value.
    if (asyncGetResponse != null) {
        asyncGetResponse.processFinish(result);
    }
}

}

快乐编码…

解决了

此解决方案正在等待单击事件并返回值

private boolean resultValue;

public boolean getDialogValueBack(Context context)
{
     final Handler handler = new Handler()
{

@Override
public void handleMessage(Message mesg)
{
    throw new RuntimeException();
} 
};

AlertDialog.Builder alert = new AlertDialog.Builder(context);
    alert.setTitle("Title");
    alert.setMessage("Message");
    alert.setPositiveButton("Return True", new 
    DialogInterface.OnClickListener()
    {
        public void onClick(DialogInterface dialog, int id)
    {
       resultValue = true;
       handler.sendMessage(handler.obtainMessage());
    }
});
    alert.setNegativeButton("Return False", new DialogInterface.OnClickListener()
  {
   public void onClick(DialogInterface dialog, int id)
  {
      resultValue = false;
       handler.sendMessage(handler.obtainMessage());
  }   
   });
      alert.show();

  try{ Looper.loop(); }
  catch(RuntimeException e){}

  return resultValue;
  }

public class AsyncGet extends AsyncTask<Void, Void, String> {

public interface AsyncGetResponse {
    void processFinish(String result);
}

private AsyncGetResponse asyncGetResponse = null;

public AsyncGet(AsyncGetResponse asyncGetResponse) {
    this.asyncGetResponse = asyncGetResponse;
}

@Override
protected void onPreExecute() {
    super.onPreExecute();

    // show progress dialog. If you need
}

@Override
protected String doInBackground(Void... voids) {

    String result = null;

    // do your background work here. Like API calls.

    return result;
}

@Override
protected void onProgressUpdate(Void... values) {
    super.onProgressUpdate(values);

    // update progress percentage. If you need.
}

@Override
protected void onPostExecute(String result) {
    super.onPostExecute(result);

    // hide progress dialog. If showing.

    // pass result value.
    if (asyncGetResponse != null) {
        asyncGetResponse.processFinish(result);
    }
}

}

new AsyncGet(new AsyncGet.AsyncGetResponse() {
                    @Override
                    public void processFinish(String result) {
                        // process result from Async task.
                    }
                }).execute();
