Android(安卓)自定义Progress Bar

Android 提供ProgressDialog，可以提示进度，但你也可以自己实现，示例如下：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_gravity="center_vertical" android:layout_width="fill_parent"android:layout_height="wrap_content"><ProgressBar android:layout_width="wrap_content"android:layout_height="wrap_content" android:id="@+id/progressbar_default"android:scaleType="fitCenter" android:layout_alignParentLeft="true"android:layout_margin="5dip" /><ProgressBar android:layout_width="fill_parent"android:layout_height="wrap_content" style="?android:attr/progressBarStyleHorizontal"android:id="@+id/progressbar_Horizontal" android:max="100"android:layout_toRightOf="@id/progressbar_default"android:layout_margin="5dip" /><TextView android:layout_width="fill_parent"android:layout_height="wrap_content" android:id="@+id/progressbar_text"android:layout_toRightOf="@id/progressbar_default" android:paddingTop="25dip"android:layout_margin="5dip" android:text="init text"/></RelativeLayout>

public class ClearProgressDialog extends AlertDialog implementsDialogInterface.OnClickListener {private ProgressBar progressBar;private int progress = 0;protected ClearProgressDialog(Context context) {super(context);init();}public ClearProgressDialog(Context context, boolean cancelable,OnCancelListener cancelListener) {super(context, cancelable, cancelListener);init();}public ClearProgressDialog(Context context, int theme) {super(context, theme);init();}public void init() {View view = getLayoutInflater().inflate(R.layout.progresslayout,null);progressBar = (ProgressBar) view.findViewById(R.id.progressbar_Horizontal);setButton(getContext().getText(R.string.stop), this);setIcon(R.drawable.andclear);setTitle(R.string.clear_progress);setView(view);//progressBar = (ProgressBar) findViewById(R.id.progressbar_Horizontal);}public void onClick(DialogInterface dialog, int which) {}Handler pHandle = new Handler() {public void handleMessage(Message msg) {}};public void setProgress(int per, String str) {}public void stop() {}}
