我目前正在使用umano slidinguppanel进行我的一个测试项目,但是我确实遇到了一个问题,我想让面板只在我按下(不是点击)并拖动某个图像或者点击按钮本身它会扩展。后者有点容易实现,但对于媒体而言,我很难实现它。

这里有一个更好的视觉效果是我的面板XML:

<com.sothree.slidinguppanel.SlidingUpPanelLayout
            xmlns:sothree="http://schemas.android.com/apk/res-auto"
            android:id="@+id/sliding_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="bottom"
            android:background="#00ffffff"
            sothree:panelHeight="120dp"
            sothree:shadowHeight="0dp"
            sothree:overlay="true"
            sothree:fadeColor="@android:color/transparent">

            <RelativeLayout
                android:orientation="vertical"
                android:layout_width="match_parent"
                android:layout_height="match_parent">

                <ImageView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:id="@+id/imageView2"
                    android:src="@drawable/test_img"
                    android:adjustViewBounds="true"
                    android:scaleType="centerCrop" />

                <ImageView
                    android:layout_width="40dp"
                    android:layout_height="40dp"
                    android:id="@+id/ic_menu"
                    android:src="@drawable/menu"
                    android:layout_marginLeft="5dp"
                    android:layout_marginTop="5dp"
                    android:onClick="showDrawer" />

            </RelativeLayout>

            <LinearLayout
                android:orientation="vertical"
                android:layout_width="fill_parent"
                android:layout_height="match_parent"
                android:background="#00ffffff">

                <LinearLayout
                    android:orientation="horizontal"
                    android:layout_width="match_parent"
                    android:layout_height="50dp"
                    android:background="#00ffffff"
                    android:id="@+id/transparent_panel">

                    <ImageView
                        android:layout_width="40dp"
                        android:layout_height="40dp"
                        android:id="@+id/ic_menu2"
                        android:layout_marginLeft="5dp"
                        android:layout_marginTop="5dp"
                        android:onClick="showDrawer"
                        android:visibility="gone"
                        android:src="#00ffffff" />

                    <LinearLayout
                        android:orientation="horizontal"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:gravity="center">

                        <ImageView
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:id="@+id/img_expand"
                            android:src="@drawable/img_expand" />
                    </LinearLayout>

                </LinearLayout>

                <LinearLayout

                    android:layout_height="match_parent"
                    android:background="#66ffffff"
                    android:id="@+id/pager_container">

                    <android.support.v4.view.ViewPager
                        android:id="@+id/pager"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent" >

                    <android.support.v4.view.PagerTitleStrip
                            android:id="@+id/pager_title"
                            android:background="@color/yellow"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:layout_gravity="top"/>

                    </android.support.v4.view.ViewPager>

                </LinearLayout>

            </LinearLayout>
        </com.sothree.slidinguppanel.SlidingUpPanelLayout>

这里我有一个带图像的面板,我想在扩展抽屉时成为手柄,在我的代码中我试图实现这个:

ImageView img_expand = (ImageView) findViewById(R.id.img_expand);

        slideLayout = (SlidingUpPanelLayout) findViewById(R.id.sliding_layout);
        slideLayout.setSlidingEnabled(false);

        img_expand.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                Log.e("Test", String.valueOf(event));
                Log.e("Test2", String.valueOf(event.ACTION_DOWN));
                Log.e("Test3", String.valueOf(event.getAction()));
                Log.e("Test4", String.valueOf(MotionEvent.ACTION_DOWN));
                Log.e("Test5", String.valueOf(MotionEvent.ACTION_MOVE));

                if (event.getAction() == MotionEvent.ACTION_MOVE || event.getAction() == MotionEvent.ACTION_DOWN) {
                    slideLayout.setSlidingEnabled(true);
                    return true;
                }else{
                    slideLayout.setSlidingEnabled(false);
                    return false;
                }
            }
        });

可悲的是,它并没有像我预期的那样奏效。希望有人可以指导我。 :d
