我在ActionBar上添加了一个Refresh按钮,但问题是我的ActionBar上总是有这个刷新按钮。我听说我必须创建一个
这是我添加图标的地方:
<item android:id="@+id/ofertasRefresh"
android:icon="@drawable/ic_action_refresh"
android:title="Refresh"
android:alphabeticShortcut="r"
android:orderInCategory="1"
android:showAsAction="always" />
然后我在我的Activity上添加了这么多代码:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
this.optionsMenu = menu;
MenuInflater inflater = getMenuInflater(); //ERROR<-----------
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu); // in Fragment cannot be applied <------------
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.airport_menuRefresh:
// Complete with your code
return true;
}
return super.onOptionsItemSelected(item);
}
public void setRefreshActionButtonState(final boolean refreshing) {
if (optionsMenu != null) {
final MenuItem refreshItem = optionsMenu
.findItem(R.id.ofertasRefresh);
if (refreshItem != null) {
if (refreshing) {
refreshItem.setActionView(R.layout.actionbar_indeterminate_progress);
} else {
refreshItem.setActionView(null);
}
}
}
}
在getMenuInflater()
上说“Cannont解析方法”,然后在“显示”中“在片段中无法应用”...
EDITED *
我认为我的问题主要集中在MyActivity.java上,然后我粘贴了OnCreateOptionsMenu
和onOptionsItemSelected
MyActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// toggle nav drawer on selecting action bar app icon/title
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action bar actions click
switch (item.getItemId()) {
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
有什么想法解决这个问题?

如果您从“活动使用”中致电
@Override
public boolean onCreateOptionsMenu(Menu menu) {
//this.optionsMenu = menu;
//MenuInflater inflater = getMenuInflater(); //ERROR<-----------
getMenuInflater().inflate(R.menu.main, menu);
//return super.onCreateOptionsMenu(menu); // in Fragment cannot be applied <------------
return true;
}
以onCreateOptionsMenu
方法夸大菜单。
并且,正如评论所说,只需从同一方法返回true
。
如果从片段调用,该方法看起来会略有不同:
@Override
public void onCreateOptionsMenu(
Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
}

像这样使用:
<强> MainActivity.java:强>
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.search: // it is going to refer the search id name in main.xml
//add your code here
return true;
default:
return super.onOptionsItemSelected(item);
}
}
<强> main.xml中:强>
<menu 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" >
<item
android:id="@+id/search"
android:icon="@drawable/ic_action_settings" --> add a icon in drawable that will display in the top of the action bar.
android:title="@string/search"
android:showAsAction="always"/>
</menu>
在上面的代码的帮助下,您将在操作栏的顶部获得一个菜单项。然后您在case R.id.search:
内添加的代码将执行该功能。
