1、普通进度条
android:id="@+id/firstBar"
//设置进度条的样式为水平的
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="200dp"
android:layout_height="wrap_content"
//设置进度条为不可见
android:visibility="gone" />
2、圆形进度条
android:id="@+id/secondBar"
//设置进度条的样式为圆的
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"
点击(此处)折叠或打开
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); //将第一个进度条设置为可见
secondbar.setVisibility(View.VISIBLE);//将第二个进度条设置为可见
}
else if(i 100)
//在第一个进度条里有两个进度
firstbar.setProgress(i); //设置进度条走到哪里
firstbar.setSecondaryProgress(i+10);//设置进度条走到哪里
secondbar.setProgress(i);
else if(i>=100)
i=0;
else
firstbar.setVisibility(View.GONE);//将进度条设置为不可见
secondbar.setVisibility(View.GONE);//将进度条设置为不可见
i=i+10;
}
});
}
}
3、带滑块的进度条seekBar
seekBar的使用方法：
1、在布局文件中声明SeekBar
android:id="@+id/seekBar"
android:layout_width="fill_parent"
/>
2、定义一个OnSeekBarChangeListener,也就是为SeekBar设置监听器
class SeekBarListener implements OnSeekBarChangeListener{
//当进度条发生改变的时候调用该函数，注意，这里的改变包括进度条自动变化，或者用手拖动进度条的滑块
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser)
{
// TODO Auto-generated method stub
}
@Override
//当用户开始拖动滑块时调用该函数
public void onStartTrackingTouch(SeekBar seekBar)
//当用户停止拖动滑块时调用该函数
public void onStopTrackingTouch(SeekBar seekBar)
源代码
private SeekBar seekBar = null;
seekBar = (SeekBar)findViewById(R.id.seekBar);
seekBar.setOnSeekBarChangeListener(new SeekBarListener());
class SeekBarListener implements OnSeekBarChangeListener{
boolean fromUser)
//打印当前进度条的位置
System.out.println(progress);
//当用户开始拖动滑块时，进度条的位置
System.out.println("start-->" + seekBar.getProgress());
//当用户停止拖动滑块时，进度条的位置
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;
布局文件
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、星状进度条RatingBar
/*RatingBar的使用方法
* 1、在布局文件中声明一个RatingBar
*
android:id="@+id/ratingBar"
//设置ratingBar的星的个数
android:numStars="5"
//设置每一次拖动走的大小为1个星
android:stepSize="1.0"
2、定义一个OnRatingBarListener，为ratingBar设置监听器
class RatingBarListener implements RatingBar.OnRatingBarChangeListener{
//当用户拖动ratingBar时调用该函数
public void onRatingChanged(RatingBar ratingBar, float rating,
}
*/
源代码
private RatingBar ratingBar = null;
//找打ratingBar
ratingBar = (RatingBar)findViewById(R.id.ratingBar);
//绑定监听器
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"
