Question

我有一个自定义ProgressDialog，其中包含一个自定义drawable，调用Async任务的预执行，如下所示

 private ProgressDialog progressDialog = new ProgressDialog(BNMlogin.this);

    @Override
    protected void onPreExecute() {

          progressDialog.setMessage("Authenticating Credentials....");
          progressDialog.setIndeterminate(true); 
          progressDialog.setIndeterminateDrawable(getResources().getDrawable(R.drawable.progress_dialog_icon_drawable_animation));
          progressDialog.show();



                 }

drawable是一个动画列表

<item android:drawable="@drawable/icon_progress_dialog_drawable_1" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_2" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_3" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_4" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_5" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_6" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_7" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_8" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_9" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_10" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_11" android:duration="150" />
<item android:drawable="@drawable/icon_progress_dialog_drawable_12" android:duration="150" />

崩溃时出现以下错误 ......

Answer 1

我不知道你为什么特意使用onpreexecute。如果要创建自定义对话框，可以参考此处 https://stackoverflow.com/a/26821095/1554031

Answer 2

试

    progressDialog.setIndeterminateDrawable(getDrawable(R.drawable.progress_dialog_icon_drawable_animation));

自定义ProgressDialog与Indeterminate Drawable无法正常工作
