Android在将图像附加到短信/彩信的可能性中选择您的应用程序

Question

我很难找到信息，该怎么做才能实现：

1. 用户正在发送短信

2. 单击附件以添加图像

3. 您的应用程序还会显示其他可能性

我应该向我的主活动或清单添加任何内容吗？

编辑：解决方案在下面的答案中。

如何将所选图像从应用程序返回到短信/彩信？

我的代码再次开始共享操作，因此您需要再次输入接收器，这不是最佳的：

 public class StartActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);

Intent myIntent = getIntent();
final int image = myIntent.getExtras().getInt("image");
ImageView imagefull = (ImageView)findViewById(R.id.imageView1);
imagefull.setImageResource(image);


Button share = (Button) findViewById (R.id.buttonshare);
share.setOnClickListener(new OnClickListener() 
{
    @Override
    public void onClick(View arg0) {
        Bitmap bitmap;
        OutputStream output;    
        bitmap = BitmapFactory.decodeResource(getResources(),
        image);
        File filepath = Environment.getExternalStorageDirectory();
        File dir = new File(filepath.getAbsolutePath() + "/Shared Movie Quotes/");
        dir.mkdirs();
        File file = new File(dir, "quote.png");
        try {
            // Share Intent
            Intent share = new Intent(Intent.ACTION_SEND);
            // Type of file to share
            share.setType("image/jpeg");
            output = new FileOutputStream(file);
            // Compress into png format image from 0% - 100%
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
            output.flush();
            output.close();
            // Locate the image to Share
            Uri uri = Uri.fromFile(file);
            // Pass the image into an Intnet
            share.putExtra(Intent.EXTRA_STREAM, uri);
            // Show the social share chooser list
            startActivity(Intent.createChooser(share, "Let them know!"));
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    } );

尝试添加以下意图过滤器：

    <activity android:name="YourActivity">
        <!-- filter for showing when image is selected -->
        <intent-filter>
    <action android:name="android.intent.action.GET_CONTENT" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>
    </activity>
