我需要不断更新。其中被添加到一个ProgressDialog为查看自定义布局的定制进度。如何更新ProgressDialog中的progressBar?
自定义布局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
xmlns:tools="http://schemas.android.com/tools"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:background="@android:color/transparent" >
<com.android.library.circleprogress.ArcProgress
android:id="@+id/arc_progress"
android:background="@android:color/transparent"
android:layout_width="200dp"
android:layout_height="200dp"
custom:arc_progress="5"
custom:arc_stroke_width="10dp"
android:layout_centerInParent="true"
custom:arc_bottom_text="Updating..."/>
</RelativeLayout>
的Java:
public static ProgressDialog createProgressDialog(Context mContext, ViewGroup viewGroup) {
ProgressDialog dialog = new ProgressDialog(mContext);
try {
dialog.show();
} catch (BadTokenException e) {
}
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.progress_dialog, viewGroup);
// this is the progressBar I need to update
ArcProgress arcProgress = (ArcProgress) view.findViewById(R.id.arc_progress);
dialog.setCancelable(false);
dialog.setContentView(view);
return dialog;
}
我打电话来此的doInBackground方法创建对话框从的AsyncTask,所以我需要更新的百分比数使酒吧移动。
...
protected void onPreExecute() {
super.onPreExecute();
pDialog = Util.createProgressDialog(context, null);
pDialog.show();
}
@Override
protected Integer doInBackground(String... params) {
String file = Util.getMapFiles().get(bean).toLowerCase() + ".txt";
// this download updates the pDialog.setProgress(percent)
Integer total = ftpDb.download(bean, Const.DIR_FTP_INICIO, file, pDialog);
return total;
}
任何想法,我怎么能实现这一点? With 默认ProgressDialog我可以更新没有问题的百分比栏。
您必须使用onProgressUpdate方法内的异步任务。并在后台调用publishprogress方法 – Sanket990
试试这个---> dialog.setIndeterminateDrawable(getActivity()。getResources()。getDrawable(R.layout.custom_layout)); –
