嗨我有以下xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="@+id/wrapper"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_margin="10dip"
android:weightSum="1"
android:background="#000"
android:orientation="horizontal">
<TextView
android:id="@+id/textMessage"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight = ".9"
android:layout_gravity="center"
android:layout_margin="5dip"
android:paddingLeft="10dip"
android:background="#FFF"
android:text="TEXT NOT SET"
android:textColor="@android:color/white" />
<ImageView
android:id="@+id/thumbPhoto"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight = ".1"
android:src="@drawable/ic_contact_default"/>
</LinearLayout>
</LinearLayout>
我想要做的是让我的ImageView的位置以编程方式更改到textMessage的左侧.
这可以通过将我的ImageView放在TextView上面来通过xml完成.但是我想以编程方式获得相同的结果.
假设我的适配器中有这个
public View getView(int position,View convertView,ViewGroup parent) {
View row = convertView;
if (row == null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.chat_item,parent,false);
}
wrapper = (LinearLayout) row.findViewById(R.id.wrapper);
// How should i change the position of my ImageView ??
wrapper.setGravity([some_condition] ? Gravity.LEFT : Gravity.RIGHT);
return row;
}
解决方法
试试这样….
ImageView imageView= (ImageView)yourLinearLayout.findViewById(R.id.thumbPhoto); yourLinearLayout.removeViewAt(1); yourLinearLayout.addView(0,imageView);
通过使用此行
// How should i change the position of my ImageView ??
wrapper.setGravity([some_condition] ? Gravity.LEFT : Gravity.RIGHT);
