To drag the Image on the screen I created my own class:
private class CustomImageView extends AppCompatImageView
In the constructor I want to set params:
public CustomImageView(Context context) {
super(context);
params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
params.bottomMargin = 50;
this.setScaleType(ImageView.ScaleType.CENTER_CROP);
this.setLayoutParams(params);
this.setWillNotDraw(false);
}
my activity_main.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.eleizo.firstapplication.MainActivity">
</RelativeLayout>
I want to have actually as it would be :
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.eleizo.firstapplication.MainActivity">
<ImageView
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:layout_marginBottom="50dp"
/>
</RelativeLayout>
Why string "params.bottomMargin = 50"
doesn't work? I tried to set params = new RelativeLayout.LayoutParams(val1,val2)
but it's no matter.
How set android:layout_marginBottom
in RelativeLayout by code?
try using the LayoutParams while you are adding the view in the relative layout. ViewGroup.addView(View, LayoutParams) .
Something like this.
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
params.bottomMargin = 50;
relativeLayout.addView(new CutomImageView(context), params);
