问题描述

限时删除!!

我试图在Android应用程序的操作栏共享按钮。在这里,我的code:

 进口android.content.Intent;
进口android.os.Bundle;
进口android.support.v4.app.Fragment;
进口android.support.v7.app.ActionBarActivity;
进口android.view.LayoutInflater;
进口android.view.Menu;
进口android.view.MenuInflater;
进口android.view.MenuItem;
进口android.view.View;
进口android.view.ViewGroup;
进口android.widget.ShareActionProvider;
进口android.widget.TextView;
 

和片断部分:

  {
私人字符串mForecastText;

公共PlaceholderFragment(){
    setHasOptionsMenu(真正的);
}

私人意图sharedIntentMaker(){
    意图shareIntent =新的意图(Intent.ACTION_SEND);
    shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    shareIntent.setType(text / plain的);
    shareIntent.putExtra(Intent.EXTRA_TEXT,mForecastText +#SunshineApp);
    返回shareIntent;
}
@覆盖
公共无效onCreateOptionsMenu(功能菜单,MenuInflater充气){
    inflater.inflate(R.menu.menu_detail,菜单);
    菜单项菜单项= menu.findItem(R.id.menu_action_share);
    ShareActionProvider mShareActionProvider =(ShareActionProvider)menuItem.getActionProvider();
    mShareActionProvider.setShareIntent(sharedIntentMaker());

}

@覆盖
公共查看onCreateView(LayoutInflater充气,容器的ViewGroup,
                         捆绑savedInstanceState){
    查看rootView = inflater.inflate(R.layout.fragment_detail,集装箱,假);

    TextView的textIntent =(TextView中)rootView.findViewById(R.id.textIntent);
    意向意图= getActivity()getIntent()。
    mForecastText = intent.getStringExtra(INT_PS);
    textIntent.setText(mForecastText);
    返回rootView;
}
 

当我跑我的模拟器,甚至真实设备的应用程序,我得到异常:

  AndroidRuntime:致命异常:主要java.lang.UnsupportedOperationException:这是不支持,使用MenuItemCompat.getActionProvider()
 

和它链接到onCreateOptionsMenu()的字符串:

  ShareActionProvider mShareActionProvider =(ShareActionProvider)menuItem.getActionProvider();
mShareActionProvider.setShareIntent(sharedIntentMaker());
 

我在做什么错了?

这是错误的logcat的P.S:堆栈跟踪:

解决方案

首先,你不能使用 android.widget.ShareActionProvider appcompat- V7 行动起来吧反向移植(例如, ActionBarActivity )。无论是使用 appcompat-V7 版本 ShareActionProvider 中,或将一切都交给本地操作栏。

第二,如果你坚持使用 appcompat-V7 ,那么你就不能安全地使用 getActionProvider(),因为这方法不会对API等级10及以下的存在。替换 menuItem.getActionProvider() MenuItemCompat.getActionProvider(菜单项)

FWIW,这里是一个示例项目实现 appcompat-V7 ShareActionProvider 。

I'm trying to make "Share" button in Action Bar of Android Application.Here my code:

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ShareActionProvider;
import android.widget.TextView;

and fragment part:

{
private String mForecastText;

public PlaceholderFragment() {
    setHasOptionsMenu(true);
}

private Intent sharedIntentMaker(){
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_TEXT, mForecastText + "#SunshineApp");
    return shareIntent;
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_detail, menu);
    MenuItem menuItem = menu.findItem(R.id.menu_action_share);
    ShareActionProvider mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();
    mShareActionProvider.setShareIntent(sharedIntentMaker());

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_detail, container, false);

    TextView textIntent = (TextView) rootView.findViewById(R.id.textIntent);
    Intent intent = getActivity().getIntent();
    mForecastText = intent.getStringExtra("INT_PS");
    textIntent.setText(mForecastText);
    return rootView;
}

When I run my app on emulator or even real device, I get exception:

AndroidRuntime﹕ FATAL EXCEPTION: main java.lang.UnsupportedOperationException: This is not supported, use MenuItemCompat.getActionProvider()

and it links to onCreateOptionsMenu()'s strings:

ShareActionProvider mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();
mShareActionProvider.setShareIntent(sharedIntentMaker());

What I'm doing wrong?

P.S.: Stacktrace of error from logcat:

解决方案

First, you cannot use android.widget.ShareActionProvider with the appcompat-v7 action bar backport (e.g., ActionBarActivity). Either use the appcompat-v7 version of ShareActionProvider, or move everything over to the native action bar.

Second, if you stick with appcompat-v7, then you cannot safely use getActionProvider(), as that method will not exist on API Level 10 and below. Replace menuItem.getActionProvider() with MenuItemCompat.getActionProvider(menuItem).

FWIW, here is a sample project that implements the appcompat-v7 edition of ShareActionProvider.
