java - Android 中 webview 上的 OnClick？

Question

我想像这样在 webView 上获取 Onclick 事件:

    webView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

        }
    });

    public class MyActivity extends Activity implements OnTouchListener{

    private float mDownPosX;
    private float mDownPosY;
    private float mUpPosX;
    private float mUpPosY;

    private WebView webView;

    private float MOVE_THRESHOLD_DP;

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

         setContentView(R.layout.webview_layout);

         MOVE_THRESHOLD_DP = 20.0F * act.getResources().getDisplayMetrics().density;
         webView v = (WebView) findViewById(R.id.webView);
         v.setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        switch (event.getAction()) { 
        case MotionEvent.ACTION_DOWN:
            this.mDownPosX = event.getX();
            this.mDownPosY = event.getY();
            break;
        case MotionEvent.ACTION_UP:
            this.mUpPosX = event.getX();
            this.mUpPosY = event.getY();
            if ((Math.abs(mUpPosX - this.mDownPosX) < MOVE_THRESHOLD_DP) && (Math.abs(mUpPosY - this.mDownPosY) < MOVE_THRESHOLD_DP)) {
                //your click code here
            }

        break; 
        }
        return false; 
    }
    }
