* MyImage クラスはビューを拡張し、ontouchListener を実装します * enter code here

public class MyImage extends View implement OnTouchListener {

Bitmap orignal;
Bitmap scaled;
Matrix m;
Context ctext;
ArrayList<Rect> rect;

私は 4 つの Rectangle を持っており、すべての Rectangle は diff diff Activity Rectrectangle0;に移動するために使用されます。Rectrectangle1; Rectrectangle2; Rectrectangle3; 四角形4; プライベート int X_POSITION; プライベート int Y_POSITION;

public MyImage(Context context) {
    super(context);

    ctext = context;

}


@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    // TODO Auto-generated method stub
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

}

@Override
public View findFocus() {
    // TODO Auto-generated method stub
    return super.findFocus();
}

@Override
public boolean isPressed() {
    // TODO Auto-generated method stub
    return super.isPressed();

}

@Override
public boolean isSelected() {
    // TODO Auto-generated method stub
    return super.isSelected();

}



@Override
public boolean onTouchEvent(MotionEvent event) {


     X_POSITION = (int)event.getX();
     Y_POSITION = (int)event.getY();

    System.out.println(X_POSITION + "\t" +Y_POSITION);

ここで問題が発生します。すべての長方形が同じアクティビティに対して起動する理由と、すべての長方形が異なるアクティビティに対して起動するように解決する方法がわからない

    switch (event.getAction()) {

    case MotionEvent.ACTION_DOWN:


        Intent i = new Intent(ctext , SelecterImage.class);
        ctext.startActivity(i);

    }

true を返します。

}

@Override
public void onDraw(Canvas canvas) {
    Paint paint = new Paint();

    int X_WIDTH = canvas.getWidth();
    int Y_HEIGHT = canvas.getHeight() / 2;

    System.out.println(X_WIDTH + "\n" + Y_HEIGHT);

    Paint rectanglePaint = new Paint();
    rectanglePaint.setARGB(255, 0, 0, 0);
    rectanglePaint.setStrokeWidth(2);
    rectanglePaint.setColor(Color.BLUE);

    rectangle0 = new Rect(10, 420, 60, 380);
    rectangle1 = new Rect(70, 420, 120, 380);


    rectangle2 = new Rect(130, 420, 180, 380);
    rectangle3 = new Rect(190, 420, 240, 380);
    rectangle4 = new Rect(250, 420, 300, 380);


    canvas.drawRect(rectangle0, rectanglePaint);

    canvas.drawRect(rectangle1, rectanglePaint);

    canvas.drawRect(rectangle2, rectanglePaint);

    canvas.drawRect(rectangle3, rectanglePaint);

    canvas.drawRect(rectangle4, rectanglePaint);

    scaled = Bitmap.createScaledBitmap(orignal, X_WIDTH, Y_HEIGHT, false);

    canvas.drawBitmap(scaled, 0, 0, paint);

}


void setBitmap(Bitmap bitmap) {
    // TODO Auto-generated method stub

    orignal = bitmap;

}



@Override
public boolean onTouch(View v, MotionEvent event) {
    return false;
    // TODO Auto-generated method stub




}   


}

最初に onTouchEvent が正しく動作することを確認してください (実際には X と Y が返されます)。 

@Override 
public boolean onTouchEvent(MotionEvent event) { 


    X_POSITION = (int)event.getX(); 
    Y_POSITION = (int)event.getY(); 

    if (event.getAction == MotionEvent.ACTION_DOWN)
    {
        if (rectangle0.contains(X_POSITION,Y_POSITION))
        {
           Intent i = new Intent(ctext , Activity1.class); 
           ctext.startActivity(i); 
        }
        else if (rectangle1.contains(X_POSITION,Y_POSITION))
        {
           Intent i = new Intent(ctext , Activity2.class); 
           ctext.startActivity(i); 
        }

        ....

    } 
}
