我想用填充更改ExpandableListView组指示器.
我使用自定义适配器将数据加载到ExpandableListView.
这是我的ExpandableListView xml.
<ExpandableListView
android:id="@+id/Ex_offers"
android:layout_width="250dp"
android:layout_height="400dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:childDivider="#00000000"
android:groupIndicator="@drawable/settings_selector"
android:listSelector="@android:color/transparent">
</ExpandableListView>
这是GroupView xml
<TextView
android:id="@+id/lblListHeadertwo"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@drawable/transperant_bar"
android:fontFamily="Lato"
android:paddingLeft="15dp"
android:textColor="#daac56"
android:textStyle="bold"
android:textSize="17sp"
android:paddingTop="8dp" />
这是ChildView xml
<TextView
android:id="@+id/text_offers"
android:layout_width="300dp"
android:layout_height="20dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="@drawable/transperant_bar"
android:paddingLeft="?android:attr/expandableListPreferredChildPaddingLeft"
android:textColor="#daac56"
android:textSize="14sp"/>
<ImageView
android:id="@+id/img"
android:layout_width="15dp"
android:layout_height="15dp"
android:layout_marginLeft="12dp"/>
这是输出图像,我想为此指标设置保证金.
解决方法
setIndicatorBounds(int,int)对Android 4.3无效.
他们引入了一个新方法setIndicatorBoundsRelative(int,int),它适用于4.3.
他们引入了一个新方法setIndicatorBoundsRelative(int,int),它适用于4.3.
public int GetPixelFromDips(float pixels) {
// Get the screen's density scale
final float scale = getResources().getDisplayMetrics().density;
// Convert the dps to pixels,based on density scale
return (int) (pixels * scale + 0.5f);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int width = metrics.widthPixels;
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN_MR2) {
explvList.setIndicatorBounds(width-GetPixelFromDips(35),width-GetPixelFromDips(5));
} else {
explvList.setIndicatorBoundsRelative(width-GetPixelFromDips(35),width-GetPixelFromDips(5));
}
}
