[問題] 我要如何在繪製出來的bitmap上加上按鈕

[lin790505 (舞踏linkl)]

最近練習由程式自已繪製圖片出來的程式碼

但我想讓我的bitmap在點擊下去時可以有更換圖片或是跑出toast之類的效果

也就是想當成一般botton來用

這樣的話 我應該如何更改才好呢?

程式碼如下：

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;

public class NewView extends View{
        Bitmap myBitmap;   //背景
        Bitmap tableImg;   //動作目標物
        Bitmap itemImg1;   //物件1
        Bitmap itemImg2;   //物件2
        Paint paint;
        public NewView(Context context, AttributeSet attrs){
                super(context, attrs);
                this.initBitmap();
        }
    public void initBitmap(){
        paint = new Paint();
        myBitmap = BitmapFactory.decodeResource
                        (getResources(), R.drawable.back);
        tableImg = BitmapFactory.decodeResource
                        (getResources(), R.drawable.table);
        itemImg1 = BitmapFactory.decodeResource
                        (getResources(), R.drawable.clock);
        itemImg2 = BitmapFactory.decodeResource
                        (getResources(), R.drawable.draw);
    }
    @Override
    protected void onDraw(Canvas canvas){
        super.onDraw(canvas);
        paint.setAntiAlias(true);
        paint.setColor(Color.BLACK);
        paint.setTextSize(30);
        canvas.drawBitmap(myBitmap, 0, 0, paint);
        canvas.drawText("寬："+myBitmap.getWidth(),0 , 220, paint);
        canvas.drawText("高: "+myBitmap.getHeight(), 150, 220, paint);
        canvas.drawBitmap(tableImg, 75, 300,paint);
        canvas.drawBitmap(itemImg1, 10, 10,paint);
        canvas.drawBitmap(itemImg2, 260, 10,paint);
    }
}

→ nvidia:把你畫出來的Bitmap設定在button上
→ aleelyle:有一種view叫Button
推 Wolfken:Button.setBackgroundDrawable()
推 tericky:ImageButton?
→ ckm0089:其實Android的View都可以setClickable( ture ) 然後再設
→ ckm0089:setOnClickListener就好
