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

<activityandroid:theme="@7F0C000B"android:label="@7F0B0013"android:name="EditActivity"android:taskAffinity="com.sina.weibo.newblog"android:configChanges="0x000000A0"android:windowSoftInputMode="0x00000010"><intent-filterandroid:label="@7F0B00ED"><actionandroid:name="android.intent.action.SEND"></action><categoryandroid:name="android.intent.category.DEFAULT"></category><dataandroid:mimeType="image/*"></data></intent-filter><intent-filterandroid:label="@7F0B00ED"><actionandroid:name="android.intent.action.SEND"></action><dataandroid:mimeType="text/plain"></data><categoryandroid:name="android.intent.category.DEFAULT"></category></intent-filter><intent-filterandroid:label="@7F0B00ED"><actionandroid:name="com.sina.weibo.intent.action.NEW_BLOG"></action><categoryandroid:name="android.intent.category.DEFAULT"></category></intent-filter></activity>

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
