Android实现分享和接收分享内容

Android实现分享文本：（Intent）:

Intent sendIntent =newIntent();sendIntent.setAction(Intent.ACTION_SEND);sendIntent.putExtra(Intent.EXTRA_TEXT,"This is my text to send.");sendIntent.setType("text/plain");startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));

Android实现分享图片：（Intent）:

Intent shareIntent =newIntent();shareIntent.setAction(Intent.ACTION_SEND);shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);shareIntent.setType("image/jpeg");startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));

Android实现分享多个图片：（Intent）:

ArrayList imageUris =newArrayList();imageUris.add(imageUri1);// Add your image URIs hereimageUris.add(imageUri2);Intent shareIntent =newIntent();shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);shareIntent.setType("image/*");startActivity(Intent.createChooser(shareIntent,"Share images to.."));

现在就让我们的应用可以接收其他应用分享过来的内容：
1、首先需要在接收分享信息的界面的清单文件中注册接收的ACTION：

2、现在我们的Activity可以接收到分享的内容了，现在可以去分别处理获取到的数据：

import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import java.util.ArrayList;class MyActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        Intent intent = getIntent();        String action = intent.getAction();        String type = intent.getType();        if (Intent.ACTION_SEND.equals(action)&&type!=null){            if ("text/plain".equals(type)){                dealTextMessage(intent);            }else if(type.startsWith("image/")){                dealPicStream(intent);            }        }else if (Intent.ACTION_SEND_MULTIPLE.equals(action)&&type!=null){            if (type.startsWith("image/")){                dealMultiplePicStream(intent);            }        }    }    void dealTextMessage(Intent intent){        String share = intent.getStringExtra(Intent.EXTRA_TEXT);        String title = intent.getStringExtra(Intent.EXTRA_TITLE);    }    void dealPicStream(Intent intent){        Uri uri = intent.getParcelableExtra(Intent.EXTRA_STREAM);    }    void dealMultiplePicStream(Intent intent){        ArrayList arrayList = intent.getParcelableArrayListExtra(intent.EXTRA_STREAM);    }}
