こんにちは私は<merge>
タグでレイアウトを膨らませようとしていますここに私のmain.xmlがあります:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.osmgames.kartuves.LinesLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/lines" />
</merge>
これは私のLinesLayout.javaです。
public class LinesLayout extends FrameLayout {
public LinesLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
super.onInterceptTouchEvent(event);
return false;
}
}
そして私のmain.java:
public class main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}}
そこで、以下のXMLをmain.xmlに拡張したいと思います。どうやってやるの?
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:layout_marginTop="75dp"
android:layout_marginRight="40dp"
android:src="@drawable/line" />
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:layout_marginTop="75dp"
android:src="@drawable/line" />
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:layout_marginTop="75dp"
android:layout_marginLeft="40dp"
android:src="@drawable/line" />
</FrameLayout>
これは私が取得しているログです:
