PopupMenu的简单使用

gls_more.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/action_refresh"
        android:title="refresh"/>
    
    <item
        android:id="@+id/action_first"
        android:title="first"/>
    
    <item
        android:id="@+id/action_clear"
        android:title="clear"/>
    
    <item
        android:id="@+id/action_delete_all"
        android:title="delete_all"/>
    
</menu>

java

PopupMenu menu = new PopupMenu(Activity.this, v);//v：要显示在这个view上
menu.setOnMenuItemClickListener(Activity.this);
MenuInflater inflater = menu.getMenuInflater();
inflater.inflate(R.menu.gls_more, menu.getMenu());
menu.show();

@Override
	public boolean onMenuItemClick(final MenuItem item) {
		switch (item.getItemId()) {
		case R.id.action_refresh:
			mGlucoseManager.refreshRecords();
			break;
		case R.id.action_first:
			mGlucoseManager.getFirstRecord();
			break;
		case R.id.action_clear:
			mGlucoseManager.clear();
			break;
		case R.id.action_delete_all:
			mGlucoseManager.deleteAllRecords();
			break;
		}
		return true;
