android程序在Layout中设置控件水平或垂直居中
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="@+id/logo"
android:src="@drawable/logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>在代码中linearlayout的设置切忌不要用LinearLayout.LayoutParams 设置gravity。要用linearlayout.setGravity(。。。)设置
然后把imageview放进去
