我想在LinearLayout编程方式下将ImageView对齐到右侧。我该怎么做?
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, World!"
android:layout_alignParentRight="true"/>
</RelativeLayout>
以编程方式
public void makeView(Context context) {
RelativeLayout rl = new RelativeLayout(context);
TextView tv = new TextView(context);
tv.setText("Hello, World");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams
(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
rl.addView(tv, lp);
}
ImageView view = (ImageView)findViewById(R.id.imageView);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)view.getLayoutParams();
params.gravity = Gravity.LEFT;
RelativeLayout
而不是LinearLayout
。
