Question

您好我试图使用OnTouchListener。

我的问题是它似乎不起作用。

我没有收到任何日志。

这是我的代码：

protected void onCreate(Bundle savedInstanceState) {

        requestWindowFeature(Window.FEATURE_NO_TITLE);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.check);

        comenntsBigLayout = (RelativeLayout) findViewById(R.id.comenntsBigLayout);
        sendComment = (Button) findViewById(R.id.sendComment);
        commentsLayout = (LinearLayout) findViewById(R.id.commentsLayout);
        enterComment = (EditText) findViewById(R.id.enterComment);
        imagesGrid = (GridView) findViewById(R.id.imagesGrid);
        mainLayout = (RelativeLayout) findViewById(R.id.mainLayout);

        mainLayout.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-generated method stub
                Log.i("test", "test");
                if(event.getAction() == MotionEvent.ACTION_UP)
                {
                    Log.i("test", "test1");
                    comenntsBigLayout.setVisibility(View.VISIBLE);
                    imagesGrid.setVisibility(View.GONE);
                }
                else if(event.getAction() == MotionEvent.ACTION_DOWN)
                {
                    Log.i("test", "test2");
                    comenntsBigLayout.setVisibility(View.GONE);
                    imagesGrid.setVisibility(View.VISIBLE);
                }

                return true;
            }
        });
}

我的XML：

                android:orientation="vertical" >
            </LinearLayout>
        </ScrollView>

        <EditText

            android:layout_toLeftOf="@id/sendComment"
            android:hint="Write something..."
            android:textColorHint="@color/black" />

        <Button

            android:text="Send"
            android:textColor="@color/black" />
    </RelativeLayout>

</RelativeLayout>

Answer 1

您的其他UI元素位于您尝试使用的相对布局之上，将OnTouchListeneter移动到其他视图。

Answer 2

试试这个，

mainLayout.setOnTouchListener(new View.OnTouchListener()
{
   // Implementation;
});

onTouchListener根本不工作
