//当单击按钮时，触发：public class share extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_share);    }//当单击按钮时，触发，自动调用系统分享程序列表    public void sharedSimple(View view) {        Intent sendIntent = new Intent();        //作用        sendIntent.setAction(Intent.ACTION_SEND);        //类型        sendIntent.setType("text/plain");        //分享的内容        sendIntent.putExtra(Intent.EXTRA_TEXT,"你是谁啊");        //启动系统的分享程序        startActivity(sendIntent);    }}

public class share extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_share);    }    public void sharedSimple(View view) {        Intent sendIntent = new Intent();        //作用        sendIntent.setAction(Intent.ACTION_SEND);        //类型        sendIntent.setType("text/plain");        //分享的内容        sendIntent.putExtra(Intent.EXTRA_TEXT, "你是谁啊");        //指定选择器：参数：intent ,分享列标题        startActivity(Intent.createChooser(sendIntent, "您好啊"));    }}

这里写图片描述

//分享图片： public  void  sharedImage(View view){        //图片路径        Uri uriImage = Uri.parse("./sdcard/4.jpg");        Intent sendIntent = new Intent();        //作用        sendIntent.setAction(Intent.ACTION_SEND);        //类型        sendIntent.setType("image/*");        //分享的内容        sendIntent.putExtra(Intent.EXTRA_STREAM, uriImage);        startActivity(Intent.createChooser(sendIntent,"分享图片到"));    }

这里写图片描述

//分享多个内容    public  void  multImage(View view){        //图片路径        Uri uriImage1 = Uri.parse("./sdcard/1.jpg");        Uri uriImage2 = Uri.parse("./sdcard/4.jpg");        ArrayList<Uri> list = new ArrayList<Uri>();        list.add(uriImage1);        list.add(uriImage2);        Intent sendIntent = new Intent();        //作用        sendIntent.setAction(Intent.ACTION_SEND_MULTIPLE);        //类型        sendIntent.setType("image/*");        //分享的内容        sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,list);        startActivity(Intent.createChooser(sendIntent, "分享图片到"));    }

这里写图片描述

//自已的app接收数据：会自动在分享列表程序中显示自已的app，public class ReceiverShared extends AppCompatActivity {    TextView textView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_receiver_shared);       textView = (TextView) findViewById(R.id.content);        handlerContent();    }    private void handlerContent() {        Intent intent = getIntent();        String type = intent.getType();        String action = intent.getAction();        if(Intent.ACTION_SEND.equals(action)){            if("text/plain".equals(type)){               //获取内容：                String info = intent.getStringExtra(Intent.EXTRA_TEXT);                textView.setText(info);            }        }    }}清单配置：        //接收数据的activity：        <activity            android:name=".ReceiverShared"            android:label="@string/title_activity_receiver_shared" >            <intent-filter>                <action android:name="android.intent.action.SEND"></action>                <category android:name="android.intent.category.DEFAULT"></category>                <data android:mimeType="text/plain"/>            </intent-filter>        </activity>

这里写图片描述

在标题栏上显示像qq 一样的分享图标功能：//菜单项：  <item        android:id="@+id/shares"        android:orderInCategory="200"        android:title="分享"        app:actionProviderClass="android.support.v7.widget.ShareActionProvider"        app:showAsAction="ifRoom"/>//activity类：public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.menu_main, menu);        MenuItem item = menu.findItem(R.id.shares);//一定是V7下的包        ShareActionProvider sp = (ShareActionProvider) MenuItemCompat.getActionProvider(item);        Intent intent = new Intent();        intent.setAction(Intent.ACTION_SEND);        intent.setType("text/plain");//分享的内容        intent.putExtra(Intent.EXTRA_TEXT, "你好啊1");        sp.setShareIntent(intent);        return super.onCreateOptionsMenu(menu);    }
