1、普通進度條
android:id="@+id/firstBar"
//設定進度條的樣式為水準的
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="200dp"
android:layout_height="wrap_content"
//設定進度條為不可見
android:visibility="gone" />
2、圓形進度條
android:id="@+id/secondBar"
//設定進度條的樣式為圓的
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"

點選(此處)折疊或打開
package com.example.progressbar;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
public class MainActivity extends Activity
{
private ProgressBar firstbar = null;
private ProgressBar secondbar = null;
private Button pbtn = null;
private int i = 0;
@Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
firstbar = (ProgressBar)findViewById(R.id.firstBar);
secondbar = (ProgressBar)findViewById(R.id.secondBar);
pbtn = (Button)findViewById(R.id.pbtn);
pbtn.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
if(i == 0)
{
firstbar.setVisibility(View.VISIBLE); //将第一個進度條設定為可見
secondbar.setVisibility(View.VISIBLE);//将第二個進度條設定為可見
}
else if(i 100)
//在第一個進度條裡有兩個進度
firstbar.setProgress(i); //設定進度條走到哪裡
firstbar.setSecondaryProgress(i+10);//設定進度條走到哪裡
secondbar.setProgress(i);
else if(i>=100)
i=0;
else
firstbar.setVisibility(View.GONE);//将進度條設定為不可見
secondbar.setVisibility(View.GONE);//将進度條設定為不可見
i=i+10;
}
});
}
}
3、帶滑塊的進度條seekBar
seekBar的使用方法:
1、在布局檔案中聲明SeekBar
android:id="@+id/seekBar"
android:layout_width="fill_parent"
/>
2、定義一個OnSeekBarChangeListener,也就是為SeekBar設定監聽器
class SeekBarListener implements OnSeekBarChangeListener{
//當進度條發生改變的時候調用該函數,注意,這裡的改變包括進度條自動變化,或者用手拖動進度條的滑塊
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser)
{
// TODO Auto-generated method stub
}
@Override
//當使用者開始拖動滑塊時調用該函數
public void onStartTrackingTouch(SeekBar seekBar)
//當使用者停止拖動滑塊時調用該函數
public void onStopTrackingTouch(SeekBar seekBar)
源代碼
private SeekBar seekBar = null;
seekBar = (SeekBar)findViewById(R.id.seekBar);
seekBar.setOnSeekBarChangeListener(new SeekBarListener());
class SeekBarListener implements OnSeekBarChangeListener{
boolean fromUser)
//列印目前進度條的位置
System.out.println(progress);
//當使用者開始拖動滑塊時,進度條的位置
System.out.println("start-->" + seekBar.getProgress());
//當使用者停止拖動滑塊時,進度條的位置
System.out.println("end-->" + seekBar.getProgress());
}
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;
布局檔案
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=".MainActivity" >
TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
SeekBar
android:id="@+id/seekBar"
android:layout_width="fill_parent"
/>
/RelativeLayout>
4、星狀進度條RatingBar
/*RatingBar的使用方法
* 1、在布局檔案中聲明一個RatingBar
*
android:id="@+id/ratingBar"
//設定ratingBar的星的個數
android:numStars="5"
//設定每一次拖動走的大小為1個星
android:stepSize="1.0"
2、定義一個OnRatingBarListener,為ratingBar設定監聽器
class RatingBarListener implements RatingBar.OnRatingBarChangeListener{
//當使用者拖動ratingBar時調用該函數
public void onRatingChanged(RatingBar ratingBar, float rating,
}
*/
源代碼
private RatingBar ratingBar = null;
//找打ratingBar
ratingBar = (RatingBar)findViewById(R.id.ratingBar);
//綁定監聽器
ratingBar.setOnRatingBarChangeListener(new RatingBarListener());
class RatingBarListener implements RatingBar.OnRatingBarChangeListener{
System.out.println("ratingBar" + rating);
RatingBar
android:id="@+id/ratingBar"
android:numStars="5"
android:stepSize="1.0"
