二、SeekBar拖动条控件使用方法
1、创建SeekBar控件
<SeekBar android:id="@+id/SeekBar1" android:layout_width="match_parent" android:layout_height="wrap_content" android:progress="30" />
2、添加setOnSeekBarChangeListener监听
seekBar2.setOnSeekBarChangeListener(this);
三、代码实例

2、代码
fry.Activity01
package fry; import com.example.SeekBarDemo1.R; import android.app.Activity; import android.os.Bundle; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; import android.widget.TextView; import android.widget.Toast; public class Activity01 extends Activity implements OnSeekBarChangeListener{ private TextView textView1; private TextView textView2; private SeekBar seekBar1; private SeekBar seekBar2; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity01); textView1=(TextView) findViewById(R.id.TextView1_seekBar); textView2=(TextView) findViewById(R.id.TextView2_seekBar); seekBar1=(SeekBar) findViewById(R.id.SeekBar1); seekBar2=(SeekBar) findViewById(R.id.SeekBar2); seekBar1.setOnSeekBarChangeListener(this); seekBar2.setOnSeekBarChangeListener(this); } /* * onProgressChanged：进度条改变事件 * onStartTrackingTouch：进度条开始拖动事件 * onStopTrackingTouch：进度条停止拖动事件 * (non-Javadoc) * @see android.widget.SeekBar.OnSeekBarChangeListener#onProgressChanged(android.widget.SeekBar, int, boolean) */ @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { // TODO Auto-generated method stub if(seekBar1.getId()==R.id.SeekBar1){ Toast.makeText(this, "1111111", Toast.LENGTH_SHORT).show(); textView1.setText("seekBar1当前位置："+progress); }else{ textView2.setText("seekBar2当前位置："+progress); } } @Override public void onStartTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub if(seekBar1.getId()==R.id.SeekBar1){ textView1.setText("seekBar1开始拖动"); }else{ textView2.setText("seekBar2开始拖动："); } } @Override public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub if(seekBar1.getId()==R.id.SeekBar1){ textView1.setText("seekBar1停止拖动"); }else{ textView2.setText("seekBar2停止拖动："); } } }
/SeekBarDemo1/res/layout/activity01.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/TextView1_seekBar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="TextView1" /> <TextView android:id="@+id/TextView2_seekBar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="TextView2" /> <SeekBar android:id="@+id/SeekBar1" android:layout_width="match_parent" android:layout_height="wrap_content" android:progress="30" /> <SeekBar android:id="@+id/SeekBar2" android:layout_width="match_parent" android:layout_height="wrap_content" android:progress="60" /> </LinearLayout>
四、获得
1、设置初始进度条
android:progress="30"
2、设置setOnSeekBarChangeListener监听
seekBar1.setOnSeekBarChangeListener(this);
3、onProgressChanged：进度条改变事件
4、onStartTrackingTouch：进度条开始拖动事件
5、onStopTrackingTouch：进度条停止拖动事件
