问题描述
这是我的布局文件:
RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/imageLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:layout_gravity="center"
android:background="@color/silver">
<TextView
android:id="@+id/bottom"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:layout_alignBaseline="@id/imageLayout"
android:layout_alignBottom="@id/imageLayout"
android:background="@color/red"
android:gravity="center"
android:textColor="@color/white"
android:textSize="30sp"
/>
<TextView
android:id="@+id/above"
android:layout_width="match_parent"
android:layout_height="50dp"
android:paddingBottom="3dp"
android:layout_above="@id/bottom"
android:background="@color/blue"
android:gravity="center"
android:textColor="@color/white"
android:textSize="30sp"
</RelativeLayout>
我加入ImageViews动态名为MatchGame.xml使用以下code中的有关版面
I am adding the ImageViews Dynamically to the about layout named MatchGame.xml Using the following code
RelativeLayout re = (RelativeLayout)findViewById(R.id.imageLayout);
re.setGravity(Gravity.CENTER);
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
final ImageView img = new ImageView(this);
//do some operations with image
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(40,40);
if (j == 0) {
// rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT,
// RelativeLayout.TRUE);
}
else {
rlp.addRule(RelativeLayout.RIGHT_OF, index - 1);
}
if (i == 0) {
// rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP,
// RelativeLayout.TRUE);
}
else {
rlp.addRule(RelativeLayout.BELOW, index - cols);
}
img.setLayoutParams(rlp);
re.addView(img);
}
}
的图像添加在矩阵的形式,但视图排列在屏幕的左侧,但我想矩阵是在屏幕的中心
请帮我它非常迫切
在此先感谢!
The Images are Added in the form of the matrix but the Views are aligned to the left of the Screen But I want the Matrix to be at the center of the screenPlease Help me Its very UrgentThanks in advance!
推荐答案
正如我所说的,你可以在最初,在包装中的另一个图像矩阵 RelativeLayout的
和中央 RelativeLayout的
:
As I said you could wrap the image matrix in another RelativeLayout
and center that in in the initial RelativeLayout
:
RelativeLayout re = (RelativeLayout)findViewById(R.id.imageLayout);
RelativeLayout content = new RelativeLayout(this);
RelativeLayout.LayoutParams clp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
clp.addRule(RelativeLayout.CENTER_IN_PARENT);
content.setLayoutParams(clp);
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
// ...the current loop...
img.setLayoutParams(rlp);
content.addView(img);
}
}
re.addView(content);
另外删除安卓重力
和的android:从XML layout_gravity
属性 RelativeLayout的
。
