          />
  
  </menu>
  

  • 界面xml代码:

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:paddingBottom="@dimen/activity_vertical_margin"
      android:paddingLeft="@dimen/activity_horizontal_margin"
      android:paddingRight="@dimen/activity_horizontal_margin"
      android:paddingTop="@dimen/activity_vertical_margin"
      tools:context=".MainActivity" >
  
      <TextView
          android:id="@+id/tv"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="内涵段子" />
  
  </RelativeLayout>
  

• MainActivity界面逻辑代码:

  package com.qf.day15_actionbar_demo3;
  
  import android.os.Bundle;
  import android.app.Activity;
  import android.content.Intent;
  import android.view.Menu;
  import android.view.MenuItem;
  import android.widget.ShareActionProvider;
  import android.widget.TextView;
  
  public class MainActivity extends Activity {
  
  
      private TextView tv;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          tv = (TextView) findViewById(R.id.tv);
      }
  
      @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);
  
          MenuItem item = menu.findItem(R.id.action_shared);
          ShareActionProvider provider = (ShareActionProvider) item.getActionProvider();
  
          Intent shareIntent = new Intent(Intent.ACTION_SEND);
          shareIntent.setType("text/plain");//分享的数据类型   文本
          //分享的数据
          shareIntent.putExtra(Intent.EXTRA_TEXT, tv.getText().toString().trim());
  
          provider.setShareIntent(shareIntent);
  
          return true;
      }
  
  }
  

• 一个自定义ActionProvider代码:

  package com.qf.day15_actionbar_demo3;
  
  import android.content.Context;
  import android.view.ActionProvider;
  import android.view.View;
  import android.view.View.OnClickListener;
  import android.widget.TextView;
  import android.widget.Toast;
  
  public class MyProvider extends ActionProvider {
  
      private Context context;
  
  
      public MyProvider(Context context) {
          super(context);
          // TODO Auto-generated constructor stub
          this.context = context;
      }
  
      @Override
      @Deprecated
      public View onCreateActionView() {
          // TODO Auto-generated method stub
          TextView tv = new TextView(context);
  
          tv.setText("分享");
  
          tv.setOnClickListener(new OnClickListener() {
  
              @Override
              public void onClick(View v) {
                  // TODO Auto-generated method stub
                  Toast.makeText(context, "自定义的分享", 0).show();
              }
          });
  
          return tv;
      }
  
  }
