More on the example of custom widget view

Modify onDraw() of MyWidgetView.java on last exercise to add more funny text on the custom widget view.

package com.exercise.AndroidWidgetView;



import android.content.Context;

import android.graphics.Canvas;

import android.graphics.Color;

import android.graphics.Paint;

import android.graphics.Path;

import android.graphics.RectF;

import android.util.AttributeSet;

import android.view.View;



public class MyWidgetView extends View {

	

	final int MIN_WIDTH = 300;

	final int MIN_HEIGHT = 150;

	final int DEFAULT_COLOR = Color.WHITE;

	int _color;

	

	final int STROKE_WIDTH = 2;



	public MyWidgetView(Context context) {

		super(context);

		// TODO Auto-generated constructor stub

		init();

	}



	public MyWidgetView(Context context, AttributeSet attrs) {

		super(context, attrs);

		// TODO Auto-generated constructor stub

		init();

	}



	public MyWidgetView(Context context, AttributeSet attrs, int defStyle) {

		super(context, attrs, defStyle);

		// TODO Auto-generated constructor stub

		init();

	}

	

	private void init(){

		setMinimumWidth(MIN_WIDTH);

		setMinimumHeight(MIN_HEIGHT);

		_color = DEFAULT_COLOR;

	}



	@Override

	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

		// TODO Auto-generated method stub

		super.onMeasure(getSuggestedMinimumWidth(), getSuggestedMinimumHeight());

	}



	@Override

	protected void onDraw(Canvas canvas) {

		// TODO Auto-generated method stub

		

		Paint paint = new Paint();

		paint.setColor(_color);

		paint.setStrokeWidth(STROKE_WIDTH);

		canvas.drawRect(5, 5, getWidth()-5, getHeight()-5, paint);

		

		Path path;

		path = new Path();

		paint.setColor(Color.GRAY);

		paint.setTextSize(25);

		path.addArc(new RectF(25, 25, getWidth()-25, getHeight()-25), 180, 90);

		canvas.drawTextOnPath("Hello", path, 0, 0, paint);

		path = new Path();

		path.addArc(new RectF(25, 25, getWidth()-25, getHeight()-25), 0, 90);

		canvas.drawTextOnPath("Android-er", path, 0, 0, paint);

	}

	

	public void setColor(int color){

		_color = color;

	}
