Question

我有一排带按钮的回收商。这些按钮仅用于样式设置，并设置为isClickable = false。按钮在网格视图中进行布局，以便动态处理任意数量的按钮。当我单击某一行的任何地方时，我想在每个行父视图上触发onClickListener设置。

我尝试在整个视图上设置一个空的相对视图，并在其上设置onClickListener。没有结果。

的xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tool="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/selector_base_row_dark"
    android:minHeight="@dimen/grid_10x"
    android:stateListAnimator="@drawable/selector_elevation_button">

    <RelativeLayout
        android:id="@+id/answerContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginEnd="@dimen/grid_8x"
        android:layout_marginStart="@dimen/grid_3x"
        android:layout_marginTop="@dimen/grid_1x">

<android.support.v7.widget.RecyclerView
            android:id="@+id/gridAnswerView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/answerQuestionTitleTextView"
            android:layout_marginEnd="@dimen/grid_2x"
            android:layout_marginTop="@dimen/grid_1x"
            android:layout_marginBottom="@dimen/grid_1x"
            android:columnWidth="120dp"
            android:gravity="center"
            android:horizontalSpacing="@dimen/grid_1x"
            android:visibility="gone"
            tool:visibility="visible" />

    </RelativeLayout>

   <RelativeLayout
        android:id="@+id/answerRowClickableArea"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

适配器中的

：

override fun onBindViewHolder(holder: RecyclerView.ViewHolder?, position: Int) {

answerRowClickableArea.setOnClickListener(goToIndex(rowPosition))

}

我还尝试在我的切换按钮类中覆盖GestureDetector.OnGestureListener，告诉按钮只有在不可点击的情况下才会使用触摸事件。我的意图是，如果按钮没有消耗触摸事件，它将通过onClickListener传递给父。

class OvalToggleButton(context: Context, attributeSet: AttributeSet) : ToggleButton(context, attributeSet), GestureDetector.OnGestureListener {
    override fun onShowPress(e: MotionEvent?) {
    }

    override fun onSingleTapUp(e: MotionEvent?): Boolean {
        return !isClickable
    }

    override fun onDown(e: MotionEvent?): Boolean {
        return false
    }

    override fun onFling(e1: MotionEvent?, e2: MotionEvent?, velocityX: Float, velocityY: Float): Boolean {
        return true
    }

    override fun onScroll(e1: MotionEvent?, e2: MotionEvent?, distanceX: Float, distanceY: Float): Boolean {
        return true
    }

    override fun onLongPress(e: MotionEvent?) {
    }
 }

仍然没有结果。

是否有一种简单的方法可以“忽略”视图并触及背后的内容？

Answer 1

您是否尝试设置行可点击的布局？

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setClickable(true);

我通过将我的answerRowClickableArea放在相同的相对布局中并将每个边缘与我的网格视图对齐来实现它。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tool="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/selector_base_row_dark"
    android:minHeight="@dimen/grid_10x"
    android:stateListAnimator="@drawable/selector_elevation_button">

    <RelativeLayout
        android:id="@+id/answerContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_marginEnd="@dimen/grid_8x"
        android:layout_marginStart="@dimen/grid_3x"
        android:layout_marginTop="@dimen/grid_1x">

    <android.support.v7.widget.RecyclerView
                android:id="@+id/gridAnswerView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@id/answerQuestionTitleTextView"
                android:layout_marginEnd="@dimen/grid_2x"
                android:layout_marginTop="@dimen/grid_1x"
                android:layout_marginBottom="@dimen/grid_1x"
                android:columnWidth="120dp"
                android:gravity="center"
                android:horizontalSpacing="@dimen/grid_1x"
                android:visibility="gone"
                tool:visibility="visible" />

            <ImageView
                android:id="@+id/answerRowClickableArea"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_alignTop="@id/gridAnswerView"
                android:layout_alignStart="@id/gridAnswerView"
                android:layout_alignEnd="@id/gridAnswerView"
                android:layout_alignBottom="@id/gridAnswerView" />

        </RelativeLayout> 
</RelativeLayout>

如果它不可点击，则单击后面的视图（isClickable = false）
