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"
android:windowSoftInputMode="0x00000010"

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
