RadioGroup变为按钮工具条

本文主要是介绍RadioGroup变为按钮工具条，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

xml设置

  
<RadioGroup android:id="@+id/MusicList_RadioGroup"android:orientation="horizontal" android:layout_alignParentBottom="true"android:layout_width="match_parent" android:layout_height="wrap_content"android:padding="2.0dip"android:background="@drawable/radiogroup_bg"><RadioButton android:id="@+id/MusicList_RadioGroup_next" android:drawableLeft="@drawable/radiogroup_next"android:text="@string/Text_radiogroup_next"android:textSize="15.0dip"android:layout_weight="1.0" android:button="@null"android:layout_width="wrap_content" android:layout_height="wrap_content"/>        <RadioButton android:id="@+id/MusicList_RadioGroup_playAndpuse" android:drawableLeft="@drawable/radiogroup_play"android:text="@string/Text_radiogroup_play"android:textSize="15.0dip"android:layout_weight="1.0" android:button="@null"android:layout_width="wrap_content" android:layout_height="wrap_content"/>                <RadioButton android:id="@+id/MusicList_RadioGroup_previous" android:drawableLeft="@drawable/radiogroup_previous"android:text="@string/Text_radiogroup_previous"android:textSize="15.0dip"android:layout_weight="1.0" android:button="@null" android:layout_width="wrap_content" android:layout_height="wrap_content"/>            </RadioGroup>  

绑定监听的代码　　

  
        //绑定监听器
        MusicListTable_RadioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener(){public void onCheckedChanged(RadioGroup arg0, int rid) {switch(rid){case R.id.MusicList_RadioGroup_next://下一首
                        break;case R.id.MusicList_RadioGroup_previous://上一首
                        break;case R.id.MusicList_RadioGroup_playAndpuse://播放或暂停
                        if(isPlaying){Drawable dr= res.getDrawable(R.drawable.radiogroup_play);//setBounds如果不设置的话setCompoundDrawables就会没有图片显示出来，所以一定要设置一次
                            dr.setBounds(0, 0, dr.getMinimumWidth(), dr.getMinimumHeight());palyAndpuse.setCompoundDrawables(dr, null,null, null);//为RadioButton设置图片，左右上下对应xml的android:drawableLeft="@drawable/XXX"
                            isPlaying=false; }else{Drawable dr= res.getDrawable(R.drawable.radiogroup_puse);dr.setBounds(0, 0, dr.getMinimumWidth(), dr.getMinimumHeight());palyAndpuse.setCompoundDrawables(dr, null,null, null);isPlaying=true;                 }arg0.clearCheck();//清除选择，如果不清除的话不能重复选择同一个Radiobutton
                        break;}}});}
