调用android手机微博客户端发送微博

用隐式意图打开android手机中安装的微博客户端发送微博。

反编译一下新浪微博的AndroidManifest.xml，发送微博的EditActivity

<activity
			android:theme="@7F0C000B"
			android:label="@7F0B0013"
			android:name="EditActivity"
			android:taskAffinity="com.sina.weibo.newblog"
			android:configChanges="0x000000A0"

反编译一下新浪微博的EditActivity

EditActivity中的oncreate方法中重要代码

File localFile1 = Environment.getExternalStorageDirectory();
    StringBuilder localStringBuilder = new StringBuilder("tmp_bmp_");
    long l = SystemClock.currentThreadTimeMillis();
    String str3 = l + ".jpg";
    File localFile2 = new File(localFile1, str3);
    this.sdcardTempFile = localFile2;
    LauchMode localLauchMode = (LauchMode)getIntent().getSerializableExtra("com.sina.weibo.intent.extra.LAUCH_MODE");
    onLauchModeChanged(localLauchMode);

private void onLauchModeChanged(LauchMode paramLauchMode) 如果我们用的是android.intent.action.SEND即LauchMode.SHARE;

if ((!sudroid.TextUtils.isEmptyOrBlank(str1)) && (str1.equals("android.intent.action.SEND")))
      paramLauchMode = LauchMode.SHARE;

 

str2 = getIntent().getStringExtra("android.intent.extra.TEXT");
    if (!android.text.TextUtils.isEmpty(str2))
    {
      setEditText(str2);
      Editable localEditable = this.etMblog.getText();
      int j = str2.length();
      Selection.setSelection(localEditable, j);
    }
    loadShareImage();

文字信息已经在EditActivity中显示出来了 接下来要loadShareImage了

protected void loadShareImage()
  {
    Uri localUri = (Uri)getIntent().getParcelableExtra("android.intent.extra.STREAM");
    if (localUri == null)
      return;
    displayImageUri(localUri);
  }

获取到Uri之后就要 displayImageUri

private void displayImageUri(Uri paramUri)
  {
    this.mImageLoadingHelper.importBitmapFile(paramUri);
    if (!this.mImageLoadingHelper.hasBitmap())
    {
      Toast.makeText(this, 2131427539, 0).show();
      return;
    }
    displayInsertBitmap();
  }

 

如果Bitmap存在就displayInsertBitmap

Bitmap localBitmap = this.mImageLoadingHelper.createThumbnail();
        localImageView1.setImageBitmap(localBitmap);

图片就展示在EditActivity中了

 

以上信息我们就可以写出调用EditActivity的隐式意图了。

Intent intent = new Intent("android.intent.action.SEND");
        intent.setType("image/*");    
        intent.putExtra(Intent.EXTRA_SUBJECT, "分享");    
        intent.putExtra(Intent.EXTRA_TEXT, "终于可以了!!!");

intent.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:////sdcard//8.png"));
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   
        startActivity(Intent.createChooser(intent, getTitle()));

 

当发送完微博后，我放到sdcard中的图片会消失。也就是这张图片//sdcard//8.png
