Question

我向上滑动并使用setOnTouchListener向下滑动以查看布局（了解如下图所示）

图片

但是我想要向上滑动并在按下按钮时向下滑动布局而不是在OnTouchListener时。为此我在网上尝试了几乎所有的例子，但根据我的要求，我没有得到任何解决方案。所以，请点击按钮

帮我制作OnTouchListener事件

我的代码

活动

import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.RelativeLayout;

public class SwipeUpActivity extends Activity {

    RelativeLayout rlSwipeHolder, rlSwipe1, rlSwipe2;
    private float startY;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_swipe_up);

        rlSwipeHolder = (RelativeLayout) findViewById(R.id.rl_swipe_up_holder);
        rlSwipe1 = (RelativeLayout) findViewById(R.id.rl_swipe_up_1);
        rlSwipe2 = (RelativeLayout) findViewById(R.id.rl_swipe_up_2);
        rlSwipe2.setVisibility(View.GONE);



        rlSwipeHolder.setOnTouchListener(new OnTouchListener() {

            @SuppressLint("ClickableViewAccessibility")
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    startY = event.getY();
                    break;
                case MotionEvent.ACTION_UP: {
                    float endY = event.getY();

                    if (endY < startY) {
                        System.out.println("Move UP");
                        rlSwipeHolder.setVisibility(View.VISIBLE);
                        rlSwipe1.setVisibility(View.VISIBLE);
                        rlSwipe2.setVisibility(View.VISIBLE);
                    } else {
                        rlSwipeHolder.setVisibility(View.VISIBLE);
                        rlSwipe1.setVisibility(View.VISIBLE);
                        rlSwipe2.setVisibility(View.GONE);
                    }
                }

                }
                return true;
            }
        });
    }
}

布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF"
    tools:context="com.app.swipeup.SwipeUpActivity" >

    <RelativeLayout
        android:id="@+id/rl_swipe_up_holder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="#0000FF"
        android:padding="5dp" >

        <RelativeLayout
            android:id="@+id/rl_swipe_up_1"
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:background="#585858" >
        </RelativeLayout>

        <RelativeLayout
            android:id="@+id/rl_swipe_up_2"
            android:layout_width="match_parent"
            android:layout_height="30dp"
            android:layout_below="@+id/rl_swipe_up_1"
            android:background="#FE2E2E" >
        </RelativeLayout>
    </RelativeLayout>

</RelativeLayout>

修改

像这样video我必须在点击按钮时打开布局并关闭布局（或向上滑动布局并向下滑动布局）

Answer 1

创建onTouchListenr的对象。

 OnTouchListener ot = new OnTouchListener(){-------- YOUR CODE ---}

启用按钮单击

rlSwipeHolder.setOnTouchListener(ot);

禁用按钮clik

 rlSwipeHolder.setOnTouchListener(null);

Answer 2

这不是确切的解决方案，但我在这里发帖，因为它可能对其他人有所帮助。

<强>答案

我在setOnClickListener 之后看到了很多针对 setOnTouchListener的解决方案，但我没有得到。因此，我按照此link

中的说明，按照动画进行布局上下
我对代码进行了微小的更改

Android：setOnClickListener之后的setOnTouchListener
