Question

如何設置onClickListener和onTouchListenere在android中的視圖類上？

我的代碼：

package com.example.circledemo.second; 

import java.util.ArrayList; 

import android.app.Dialog; import android.content.Context; import android.graphics.Bitmap; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.graphics.Path; import android.graphics.RectF; import android.view.MotionEvent; import android.view.View; import android.view.Window; import android.widget.ImageView; import android.widget.TextView; 

import com.example.circledemo.R; 

public class SecondTCanvas extends View { 

    public Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); Context contextData; int layoutWidth, layoutHeight; 

    private Bitmap canvasBitmap; 

    public SecondTCanvas(Context context, float[] values, int width, int height) {  super(context);   contextData = context;  layoutHeight = height;  layoutWidth = width; 

     System.out.println("=== Layout .... Width : " + layoutWidth + " Height : " + layoutHeight);  } 

    public void onDraw(Canvas c) { 

     paint.setColor(Color.BLACK);  c.drawRect(0, 0, getWidth(), getHeight(), paint);  buildDrawingCache(true);  canvasBitmap = getDrawingCache(true); } 

    @Override public boolean onTouchEvent(MotionEvent event) {  if (event.getAction() == MotionEvent.ACTION_DOWN) {    // Get x and y coordinates of where the finger touched   int pixelX = (int) (Math.floor(event.getX()));   int pixelY = (int) (Math.floor(event.getY())); 

      if (canvasBitmap != null) {    } 


      invalidate();  } 

     // If the finger is off the screen  if (event.getAction() == MotionEvent.ACTION_UP) {   // alphaIndex = -1; //This is a flag to reset the view alphas to   // normal   invalidate();  } 

     return true; 

     // return super.onTouchEvent(event); } 


}

在使用OnTouchListner使用返回False現在你可以處理點擊聽者的點擊。
