您好,
我使用RelativeLayout
构建了自定义视图,以将其用作自定义图像按钮。
到目前为止,选择它工作(PIC2),甚至当我点击它(使用GoogleTV Remote)时,视图成功地将其状态更改为PIC3(感谢android:duplicateParentState="true"
)
但不幸的是onClickListener
没有触发(如果我点击带有遥控器的视图“确定”按钮或者我使用触摸板,则无关紧要。)
我真的需要像普通按钮一样的行为。
怎么做到这一点?我已经花了几个小时来搜索Google和StackOverflow ...(顺便说一下。当为android:clickable="false"
设置RelativeLayout
时,OnClickListener
正在运行,但只有当我使用鼠标指针时(触摸板)然后焦点丢失,状态(图3)不显示)

我现在得到了......解决方案非常简单,需要一些时间; - )
覆盖RoundedButton.java中的dispatchKeyEvent(KeyEvent event)
并实现自己的OnClickListener。然后写一个公共setOnClickListener
函数......
private OnClickListener listener;
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
if(listener != null) listener.onClick(this);
}
return super.dispatchTouchEvent(event);
}
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_UP && (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_CENTER || event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
if(listener != null) listener.onClick(this);
}
return super.dispatchKeyEvent(event);
}
public void setOnClickListener(OnClickListener listener) {
this.listener = listener;
}
public class RoundedButton extends RelativeLayout
{
private OnClickListener listener;
private String label;
private int icon;
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
if(listener != null) listener.onClick(this);
}
return super.dispatchTouchEvent(event);
}
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_UP && (event.getKeyCode() == KeyEvent.KEYCODE_DPAD_CENTER || event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
if(listener != null) listener.onClick(this);
}
return super.dispatchKeyEvent(event);
}
public void setOnClickListener(OnClickListener listener) {
this.listener = listener;
}

答案 1 :(得分:1)
我正在RelativeLayout
中创建自定义视图的实例(继承自RecyclerView.Adapter
)并将list_item.xml
扩展到每个新实例中,然后将我的侦听器附加到{{1} }方法,但即使理论上我正在以正确的方式做事在我从onBindViewHolder()
(我的自定义视图)&#39中删除android:clickable="true"
属性之前它没有工作; s根布局。
