[android help] Change GRAVIITY and SIZE of View programmatically

Change GRAVIITY and SIZE of View programmatically

I would like to change the size of my View (CanvasView extends View) programmatically maintaining gravity. My View is inside FrameLayout, which is inside of RelativeLayout. I tried many different approaches but I am stuck...

The point is, that I would like to set size depending on screen size:

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        ToolsAndConstants.metrics = new DisplayMetrics();

        windowManager =  (WindowManager) getSystemService(Context.WINDOW_SERVICE);
        windowManager.getDefaultDisplay().getMetrics(ToolsAndConstants.metrics);

        setContentView(R.layout.activity_dictionary);

        CanvasView canvasView = (CanvasView)         findViewById(R.id.activity_dictionary_CanvasView);
        canvasView.canvasWidth  = (ToolsAndConstants.metrics.widthPixels / 10 * 7) - 10;
        canvasView.canvasHeight = (ToolsAndConstants.metrics.heightPixels / 10 * 4) - 10; 
        canvasView.setLayoutParams(new RelativeLayout.LayoutParams(canvasView.canvasWidth, canvasView.canvasHeight));

        CanvasView canvasView = (CanvasView) findViewById(R.id.activity_dictionary_CanvasView);
        canvasView.canvasWidth  = (ToolsAndConstants.metrics.widthPixels / 10 * 7) - 10;
        canvasView.canvasHeight = (ToolsAndConstants.metrics.heightPixels / 10 * 4) - 10; 
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ToolsAndConstants.metrics.widthPixels / 10 * 7, (ToolsAndConstants.metrics.heightPixels / 10 * 4) - 10, Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM);
        FrameLayout fl = (FrameLayout) findViewById(R.id.activity_dictionary_frameLayout1);
        fl.setLayoutParams(params);
        canvasView.setLayoutParams(params);

    (...)
    }

XML file:

    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_dictionary_relativeLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:layout_centerHorizontal="true"
        android:gravity="center_vertical|center_horizontal"
        android:orientation="vertical" >

                    android:id="@+id/activity_dictionary_progressBar1"
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal" />

                    android:id="@+id/activity_dictionary_textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:text="Loading dictionary..."
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="@android:color/white" />
    

            android:id="@+id/activity_dictionary_frameLayout1"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" >

                    android:id="@+id/activity_dictionary_CanvasView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="0dp"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            class="com.example.dictionary.CanvasView"
            android:orientation="vertical" />
    

How can I resize it?
