I had made a simple camera app and was thinking about customizing the view. Currently, I've been stuck with a problem with the ImageView not being able to be displayed on the top of the framelayout. Is there something wrong with the xml code below ? Or should I set some parameter in the code ? All I want to do is to display the Imageview above the framelayout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout
android:id="@+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
>
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right|center_vertical">
<ImageView
android:id="@+id/button_capture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/shot_dot_icn" />
</LinearLayout>
</FrameLayout>
</LinearLayout>
Try this layout, I am not sure if I understand your requirement though.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="@+id/button_capture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/shot_dot_icn" />
<FrameLayout
android:id="@+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right|center_vertical">
</LinearLayout>
</FrameLayout>
</LinearLayout>
I solved the problem with the script below. All I had to do was to set the bringToFront() to the ImageView to set the view on top of the Framelayout.
ImageView captureButton = (ImageView) findViewById(R.id.button_capture);
captureButton.bringToFront();
