用 微信的 android SDK 怎么分享信息 到微信

1. 微信官方SDK的分享方法。

   //图片

   Bitmap bt=BitmapFactory.decodeResource(getApplicationContext().getResources(), R.drawable.erweima);        final Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(getContentResolver(), bt, null,null));

//分享到朋友

private void shareToFriend(Uri uri) {

Intent intent = new Intent();
ComponentName comp = new ComponentName("com.tencent.mm",
"com.tencent.mm.ui.tools.ShareImgUI");
intent.setComponent(comp);
intent.setAction("android.intent.action.SEND");
intent.setType("image/*");
//intent.setFlags(0x3000001);
intent.putExtra(Intent.EXTRA_STREAM,uri);
startActivity(intent);
}

1. 调用分享文本的android 系统方法。

//分享文字
public void shareText(View view) {
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, "This is my Share text.");
shareIntent.setType("text/plain");

//设置分享列表的标题，并且每次都显示分享列表
startActivity(Intent.createChooser(shareIntent, "分享到"));
}

//分享单张图片
public void shareSingleImage(View view) {
String imagePath = Environment.getExternalStorageDirectory() + File.separator + "test.jpg";
//由文件得到uri
Uri imageUri = Uri.fromFile(new File(imagePath));
Log.d("share", "uri:" + imageUri);  //输出：file:///storage/emulated/0/test.jpg

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "分享到"));
}

//分享多张图片
public void shareMultipleImage(View view) {
ArrayList uriList = new ArrayList<>();

String path = Environment.getExternalStorageDirectory() + File.separator;
uriList.add(Uri.fromFile(new File(path+"australia_1.jpg")));
uriList.add(Uri.fromFile(new File(path+"australia_2.jpg")));
uriList.add(Uri.fromFile(new File(path+"australia_3.jpg")));

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND_MULTIPLE);
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uriList);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "分享到"));
}
