我一直在实施FloatingActionButton
但不知何故一直没有做出回应。没有错误,没有任何反应。
以下是Java
和xml
代码:
我已使用Log Event
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.e("ABCD","ABCD");
}
});
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

让我们将Toolbar
和AppbarLayout
放在fab
下方,看看会发生什么:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<LinearLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<!-- include your layout here -->
</LinearLayout>
<!-- when the screen is loading, in your case optional -->
<LinearLayout
android:id="@+id/progress"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="gone">
<include layout="@layout/layout_loading"></include>
</LinearLayout>
<!-- when the screen is empty no data, in your case optional -->
<LinearLayout
android:id="@+id/empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="gone">
<include layout="@layout/layout_empty"></include>
</LinearLayout>
<!-- a fab -->
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
app:backgroundTint="#009688"
style="@style/FabStyle"
android:layout_gravity="bottom|end"
android:layout_marginBottom="20dp"
android:visibility="invisible" />
<!-- the toolbar layout -->
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:title="@string/app_name"
app:layout_collapseMode="pin"
app:popupTheme="@style/ThemeOverlay.AppCompat.Dark" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
首先检查没有内容的fab点击,然后使用内容线性布局中的内容进行尝试。
我将您的布局修改为此(删除了所有内容),然后点击即可 工作
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!--<include layout="@layout/content_main" />-->
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:layout_gravity="bottom|end"
android:clickable="true"
android:src="@android:drawable/ic_dialog_email"
app:backgroundTint="#FF0000"
app:rippleColor="#FFF" />
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
因此,您的网格视图必须占用所有点击直通,让我检查并再次返回。

毕竟它不是GridView
。代码中有一条不必要的行。
Voila发现了您的问题,请在onPostExecute()
ParseActivity
MainActivity.this.setContentView(R.layout.activity_main);
可能在第286行附近。
这会再次设置布局,并且不会注册on click侦听器,这就是为什么当它在布局文件(DownloadZip)中时,它正在工作。
如果有必要,请重新启动布局,即找到fab并放入另一个setOnClickListener。您可以将这些代码放在方法中,并在需要重新布局的位置调用它们。

将activity_main的代码替换为:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"></android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="20dp"
android:src="@android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>

代码是对的。您确定要覆盖
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState)
而不是
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_incoming_call);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fabCall);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d("mylog" , "it happens...");
}
});
}
示例:
MbMessage outMessage = new MbMessage();
//copy message headers if required
MbElement oRoot = outMessage.getRootElement();
MbElement oBody = oRoot.createElementAsLastChild(MbBLOB.PARSER_NAME);
oBody.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "BLOB", yourXmlAsByteArray);
MbMessageAssembly outAssembly = new MbMessageAssembly(inAssembly, inAssembly.getLocalEnvironment(), inAssembly.getExceptionList(), outMessage);
