Question

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout /* not important */>

    <TextView /* not important */ />

    <TextView /* not important */ />

    <RelativeLayout
        /* not important */ 
        android:id="@+id/detailLayout"
        android:visibility="gone">

        <TextView /* not important */ />
    </RelativeLayout>

</RelativeLayout>

private class ItemClickListener implements AdapterView.OnItemClickListener
{
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        RelativeLayout detailLayout = (RelativeLayout) view.findViewById(R.id.detailLayout);
        int detailLayoutVisibility = detailLayout.getVisibility();

        if(detailLayoutVisibility == View.GONE)
        {
            detailLayout.setVisibility(View.VISIBLE);
        }
        else
        {
            detailLayout.setVisibility(View.GONE);
        }
    }
}

首先，当我点击该项目时，事件会触发，detailLayout会将可见性更改为View.VISIBLE，但是再次尝试点击它会导致没有事件触发。

Answer 1

首先，为detailLayout创建一个全局变量，而不是每次单击时都初始化它。然后，在onCreate实施detailLayout之后，this将点击监听器onClickListener设置为AdapterView.OnItemClickListener。

另外，为什么要实施View.OnClickListener而不是RelativeLayout？您想要点击detailLayout非适配器吗？

不要只设置GONE到detailLayout的可见性，还要尝试对TextView的子视图执行相同操作，即设置detailLayout的可见性在GONE到ELASTICSEARCH_URL=http://elasticsearch-logging.kube-system:9200 {"@timestamp":"2016-04-19T02:39:08.559Z","level":"error","message":"Service Unavailable","node_env":"production","error":{"message":"Service Unavailable","name":"Error","stack":"Error: Service Unavailable\n at respond (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/transport.js:235:15)\n at checkRespForFailure (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/transport.js:203:7)\n at HttpConnector.<anonymous> (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/connectors/http.js:156:7)\n at IncomingMessage.bound (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/node_modules/lodash-node/modern/internals/baseBind.js:56:17)\n at IncomingMessage.emit (events.js:117:20)\n at _stream_readable.js:944:16\n at process._tickCallback (node.js:442:13)\n"}} {"@timestamp":"2016-04-19T02:39:08.652Z","level":"fatal","message":"Service Unavailable","node_env":"production","error":{"message":"Service Unavailable","name":"Error","stack":"Error: Service Unavailable\n at respond (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/transport.js:235:15)\n at checkRespForFailure (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/transport.js:203:7)\n at HttpConnector.<anonymous> (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/src/lib/connectors/http.js:156:7)\n at IncomingMessage.bound (/kibana-4.0.2-linux-x64/src/node_modules/elasticsearch/node_modules/lodash-node/modern/internals/baseBind.js:56:17)\n at IncomingMessage.emit (events.js:117:20)\n at _stream_readable.js:944:16\n at process._tickCallback (node.js:442:13)\n"}}内。

Answer 2

尝试将detailLayout设置为

android:clickable="false"
android:focusable="false"

另外，你说的东西不重要，很可能非常重要。

更改项目子项的可见性后，onItemClickListener将停止工作
