調用系統分享文字:
public static void shareText(Context context, String extraText) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "串連分享");
intent.putExtra(Intent.EXTRA_TEXT, extraText);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(
Intent.createChooser(intent, "串連分享"));
}
調用系統分享圖片,方法是: 1、先讀取Assets裡面的圖片轉化成Bitmap ; 2、再以檔案File形式儲存在本地; 3、最後Uri串連本地該圖片進行分享。 讀取Assets裡面的圖片轉化成Bitmap,代碼如下: private Bitmap getImageFromAssetsFile(String fileName){ Bitmap image = null; AssetManager am = getResources().getAssets(); try { InputStream is = am.open(fileName); image = BitmapFactory.decodeStream(is); is.close(); } catch (IOException e) { e.printStackTrace(); } return image;}
Bitmap以檔案File形式儲存在本地,代碼如下:
public static File saveFile(Bitmap bm,String path, String fileName) throws IOException {
File dirFile = new File(path);
if(!dirFile.exists()){
dirFile.mkdir();
}
File myCaptureFile = new File(path , fileName);
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(myCaptureFile));
bm.compress(Bitmap.CompressFormat.JPEG, 80, bos);
bos.flush();
bos.close();
return myCaptureFile;
}
調用系統原生分享圖片代碼: public static void shareImage(Context context, Uri uri, String title) { Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, uri); shareIntent.setType("image/jpeg"); context.startActivity(Intent.createChooser(shareIntent, title));} 最後Uri串連本地該圖片進行分享: Bitmap bitmap = getImageFromAssetsFile("/assets/ewcode.png"); try { File file = saveFile(bitmap, dir, "ewcode.png"); Uri uri = Uri.fromFile(file); Shares.shareImage(EWcodeActivity.this,uri,"二維碼分享"); } catch (IOException e) { e.printStackTrace(); }
