Android下的扩展SeekBar

核心提示：{// 保存SeekBar的值persistInt(coSeekBar.getProgress()+ciMinVal);// must reset initvalciInitVal = coSeekBar.getProgress()+ciMinVal;}super.onDialogClosed(positiveResu

{

// 保存SeekBar的值

persistInt(coSeekBar.getProgress()+ciMinVal);

// must reset initval

ciInitVal = coSeekBar.getProgress()+ciMinVal;

}

super.onDialogClosed(positiveResult);

}

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromTouch) {

coSeekBarValView.setText((ciMinVal+progress)+csUnit);

this.setSummary((ciMinVal+progress)+csUnit);

}

@Override

public void onStartTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

}

@Override

public void onStopTrackingTouch(SeekBar seekBar) {

// TODO Auto-generated method stub

}

}

3、SeekBar的布局xml：

< ?xml version="1.0" encoding="UTF-8"? >

< LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:paddingTop="10px"

android:paddingLeft="10px"

android:paddingRight="10px"

android:paddingBottom="10px"

android:layout_width="fill_parent"

android:layout_height="fill_parent" >

< SeekBar

android:id="@+id/SeekBarControl"

android:paddingLeft="10px"

android:paddingRight="10px"

android:layout_width="fill_parent"

android:layout_height="wrap_content"/ >

< RelativeLayout

android:layout_width="fill_parent"

android:layout_height="fill_parent" >

< TextView

android:id="@+id/SeekBarMin"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentLeft="true"

android:textSize="18px"

android:text="Min" / >

< TextView

android:id="@+id/SeekBarVal"
