Android应用程序之间共享文字和图片(一)

以下为TestReceiveShare1工程

MainActivity如下:

package cn.testreceiveshare1;import java.util.ArrayList;import android.net.Uri;import android.os.Bundle;import android.widget.ImageView;import android.widget.TextView;import android.app.Activity;import android.content.Intent;/** * Demo描述: * 非系统自带Android应用之间传递文字和图片 * 即在两个自写的应用之间传递文字和图片 *  * 注意事项: * 先部署TestReceiveShare1工程 * 再部署TestShare1工程 *  * 参考资料: * http://blog.csdn.net/xiaanming/article/details/9428613 */public class MainActivity extends Activity {private TextView mTextView;private ImageView mFirstImageView;private ImageView mSecondImageView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);initViews();handleReceivedIntent();}private void initViews(){mTextView=(TextView) findViewById(R.id.textView);mFirstImageView=(ImageView) findViewById(R.id.firstImageView);mSecondImageView=(ImageView) findViewById(R.id.secondImageView);}private void handleReceivedIntent(){Intent intent=this.getIntent();String aciton=intent.getAction();String type=intent.getType();System.out.println("aciton="+aciton+",type="+type);//情况一:欲分享的内容是文字if (aciton!=null&&type!=null&&    Intent.ACTION_SEND.equals(aciton)&&"text/plain".equals(type)) {String content=intent.getStringExtra(Intent.EXTRA_TEXT);System.out.println("content="+content);mTextView.setText(content);}//情况二:欲分享的内容是一张图片if (aciton!=null&&type!=null&&    Intent.ACTION_SEND.equals(aciton)&&"image/jpeg".equals(type)) {Uri pictureUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);if (pictureUri != null) {System.out.println("pictureUri="+pictureUri);mFirstImageView.setImageURI(pictureUri);}  }//情况三:欲分享的内容是多张图片if (aciton!=null&&type!=null&&    Intent.ACTION_SEND_MULTIPLE.equals(aciton)&&"image/jpeg".equals(type)) {ArrayList<Uri> pictureUrisArrayList = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);  if (pictureUrisArrayList.size()>0) {System.out.println("pictureUrisArrayList.size()="+pictureUrisArrayList.size());mFirstImageView.setImageURI(pictureUrisArrayList.get(0));mSecondImageView.setImageURI(pictureUrisArrayList.get(1));}  }}}

main.xml如下:

<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"     >    <TextView        android:id="@+id/textView"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world"         android:layout_centerHorizontal="true"        android:textSize="20sp"        android:layout_marginTop="50dip"    />        <ImageView        android:id="@+id/firstImageView"        android:layout_width="80dip"        android:layout_height="80dip"        android:layout_centerHorizontal="true"        android:layout_marginTop="150dip"    />         <ImageView        android:id="@+id/secondImageView"        android:layout_width="80dip"        android:layout_height="80dip"        android:layout_centerHorizontal="true"        android:layout_marginTop="290dip"    />    </RelativeLayout>

AndroidManifest.xml如下:
