Mainactivity：

package com.example.dialog1;import android.app.Activity;import android.app.ProgressDialog;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;public class MainActivity extends Activity {    private Button bt;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initViews();    }    private void initViews() {        // TODO Auto-generated method stub        bt = (Button) findViewById(R.id.bt);    }    public void myclick(View v) {        ProgressDialog pd=new ProgressDialog(this);        pd.setMax(100);        pd.setSecondaryProgress(30);        pd.setTitle("进度条：");        pd.setIcon(R.drawable.ic_launcher);        pd.setMessage("正在下载。。。");        pd.show();    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        // Handle action bar item clicks here. The action bar will        // automatically handle clicks on the Home/Up button, so long        // as you specify a parent activity in AndroidManifest.xml.        int id = item.getItemId();        if (id == R.id.action_settings) {            return true;        }        return super.onOptionsItemSelected(item);    }}

xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.dialog1.MainActivity" >    <Button        android:id="@+id/bt"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:text="progress"       android:onClick="myclick"        /></RelativeLayout>
