ProgressDialog的样式有两种，一种是圆形不明确状态，一种是水平进度条状态

第一种方式：圆形进度条

[java]
view plain
copy

final ProgressDialog dialog = new ProgressDialog(this);
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);// 设置进度条的形式为圆形转动的进度条
dialog.setCancelable(true);// 设置是否可以通过点击Back键取消
dialog.setCanceledOnTouchOutside(false);// 设置在点击Dialog外是否取消Dialog进度条
dialog.setIcon(R.drawable.ic_launcher);//
// 设置提示的title的图标，默认是没有的，如果没有设置title的话只设置Icon是不会显示图标的
dialog.setTitle("提示");
// dismiss监听
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {

@Override
public void onDismiss(DialogInterface dialog) {
// TODO Auto-generated method stub

}
});
// 监听Key事件被传递给dialog
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {

@Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
// TODO Auto-generated method stub
return false;
}
});
// 监听cancel事件
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {

@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub

}
});
//设置可点击的按钮，最多有三个(默认情况下)
dialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setButton(DialogInterface.BUTTON_NEUTRAL, "中立",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setMessage("这是一个圆形进度条");
dialog.show();
new Thread(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
try {
Thread.sleep(5000);
// cancel和dismiss方法本质都是一样的，都是从屏幕中删除Dialog,唯一的区别是
// 调用cancel方法会回调DialogInterface.OnCancelListener如果注册的话,dismiss方法不会回掉
dialog.cancel();
// dialog.dismiss();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}).start();

其中通过Thread.sleep(5000)模拟后台操作。
cancel和dismiss方法本质都是一样的，都是从屏幕中删除Dialog,唯一的区别是：调用cancel方法会回调DialogInterface.OnCancelListener如果注册的话,dismiss方法不会回掉。

第二种方式：水平进度条

[java]
view plain
copy

// 进度条还有二级进度条的那种形式，这里就不演示了
final ProgressDialog dialog = new ProgressDialog(this);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 设置水平进度条
dialog.setCancelable(true);// 设置是否可以通过点击Back键取消
dialog.setCanceledOnTouchOutside(false);// 设置在点击Dialog外是否取消Dialog进度条
dialog.setIcon(R.drawable.ic_launcher);// 设置提示的title的图标，默认是没有的
dialog.setTitle("提示");
dialog.setMax(100);

//

dialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
dialog.setButton(DialogInterface.BUTTON_NEUTRAL, "中立",
new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});

//从第13行到36行是原博主写的，但我觉得这种写法不够简洁，重新改了一下
DialogInterface.OnClickListener dialogOnclicListener=new DialogInterface.OnClickListener(){

public void onClick(DialogInterface dialog, int which) {

switch(which){

case Dialog.BUTTON_POSITIVE:

Toast.makeText(MainActivity.this, "确认" + which, Toast.LENGTH_SHORT).show();

break;

case Dialog.BUTTON_NEGATIVE:

Toast.makeText(MainActivity.this, "取消" + which, Toast.LENGTH_SHORT).show();

break;

case Dialog.BUTTON_NEUTRAL:

Toast.makeText(MainActivity.this, "忽略" + which, Toast.LENGTH_SHORT).show();

break;

}

}

};

dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消",

dialogOnclicListener );

dialog.setButton(DialogInterface.BUTTON_POSITIVE , "确定",

dialogOnclicListener );

dialog.setButton(DialogInterface.BUTTON_NEUTRAL , "忽略",

dialogOnclicListener );

dialog.setMessage("这是一个水平进度条");
dialog.show();
new Thread(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
int i = 0;
while (i < 100) {
try {
Thread.sleep(200);
// 更新进度条的进度,可以在子线程中更新进度条进度
dialog.incrementProgressBy(1);
// dialog.incrementSecondaryProgressBy(10)//二级进度条更新方式
i++;

} catch (Exception e) {
// TODO: handle exception
}
}
// 在进度条走完时删除Dialog
dialog.dismiss();

}
}).start();

更多的是使用自定义的ProgressDialog，以满足不同显示的需要。
