我正在开发一个绘画应用程序,我想在其中将Bitmap图像从一个活动传递到另一个活动,但项目没有响应.我将相对布局截图转换为位图并将其传递给Intent但问题仍未解决.这是我的代码....

DrawingActivity

package com.newdrawing;
public class DrawingActivity extends Activity {
    private Bitmap  mBitmap;
    private Canvas  mCanvas;
    private Path    mPath;
    private Paint   mBitmapPaint;
    private Paint   mPaint;
    MyDrawView myDrawView;
    RelativeLayout parent;
    Bitmap bitmap;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_drawing);

        parent = (RelativeLayout) findViewById(R.id.singleparent);
        myDrawView = new MyDrawView(this);
        parent.addView(myDrawView);
        Activity context;
        //RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
        View child = getLayoutInflater().inflate(R.layout.trans, null);
        parent.addView(child);   
   }

   public void color(View v) {
       switch (v.getId()) {
        case R.id.button3:
           parent.setBackgroundColor(Color.RED);
            break;
        case R.id.button4:
             parent.setBackgroundColor(Color.GREEN);
            break;
        case R.id.button5:
             parent.setBackgroundColor(Color.BLUE); …

我们正在开发一款应用.我们从json数组中获取数据.在那我想要替换标签.但是模拟器抛出错误.类似于无效的语法.我的代码:

top=top.replaceall("<br\/>"," ");

请帮忙.提前致谢
