代码如下：
package com.ray.draw;import java.io.InputStream;import android.app.Activity;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.Canvas;import android.graphics.Paint;import android.os.Bundle;import android.view.View;public class TestDrawBitmap extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new myView(this)); }}class myView extends View{public myView(Context context) {super(context);}protected void onDraw(Canvas canvas) {super.onDraw(canvas);//read the icon.png into bufferInputStream is = getResources().openRawResource(R.drawable.icon);//decodeBitmap mBitmap = BitmapFactory.decodeStream(is);Paint mPaint = new Paint();canvas.drawBitmap(mBitmap, 40, 40, mPaint);}}
