我怎么可以张贴在Twitter意图ACTION_SEND?(How can I post on Tw

2019-07-18 04:32发布

我一直在挣扎着从我的应用程序到Twitter发送文本。

下面的代码工作带来了应用程序,如蓝牙,Gmail中,Facebook和Twitter的列表,但是当我选择的Twitter不会预先填入文本我本来期望。

我知道身边有与Facebook这样的问题,但我必须做一些错误的,它不与Twitter合作。

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Example Text");
startActivity(Intent.createChooser(intent, "Share Text"));

Answer 1:

我用我的这个代码片段:

private void shareTwitter(String message) {
    Intent tweetIntent = new Intent(Intent.ACTION_SEND);
    tweetIntent.putExtra(Intent.EXTRA_TEXT, "This is a Test.");
    tweetIntent.setType("text/plain");

    PackageManager packManager = getPackageManager();
    List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);

    boolean resolved = false;
    for (ResolveInfo resolveInfo : resolvedInfoList) {
        if (resolveInfo.activityInfo.packageName.startsWith("com.twitter.android")) {
            tweetIntent.setClassName(
                    resolveInfo.activityInfo.packageName,
                    resolveInfo.activityInfo.name);
            resolved = true;
            break;
        }
    }
    if (resolved) {
        startActivity(tweetIntent);
    } else {
        Intent i = new Intent();
        i.putExtra(Intent.EXTRA_TEXT, message);
        i.setAction(Intent.ACTION_VIEW);
        i.setData(Uri.parse("https://twitter.com/intent/tweet?text=" + urlEncode(message)));
        startActivity(i);
        Toast.makeText(this, "Twitter app isn't found", Toast.LENGTH_LONG).show();
    }
}

private String urlEncode(String s) {
    try {
        return URLEncoder.encode(s, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        Log.wtf(TAG, "UTF-8 should always be supported", e);
        return "";
    }
}

希望能帮助到你。



Answer 2:

你可以简单地用文本打开URL和Twitter的应用程序将做到这一点。 ;)

String url = "http://www.twitter.com/intent/tweet?url=YOURURL&text=YOURTEXT";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

它也将打开浏览器的鸣叫登录,如果没有发现Twitter的应用程序。

试试这个,我用它和伟大的工作

  Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/intent/tweet?text=...."));
  startActivity(browserIntent);         


Answer 4:

首先,你必须检查是否安装在设备上的Twitter的应用程序或不那么分享到微博全文:

try
    {
        // Check if the Twitter app is installed on the phone.
        getActivity().getPackageManager().getPackageInfo("com.twitter.android", 0);
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setClassName("com.twitter.android", "com.twitter.android.composer.ComposerActivity");
        intent.setType("text/plain");
        intent.putExtra(Intent.EXTRA_TEXT, "Your text");
        startActivity(intent);

    }
    catch (Exception e)
    {
        Toast.makeText(getActivity(),"Twitter is not installed on this device",Toast.LENGTH_LONG).show();

    }

对于在Twitter上分享文字图片 ,更多的代码控制版本低于,您可以添加更多的方法来与共享的WhatsApp , Facebook的 ...这是官方应用程序,如果程序不存在不开的浏览器。

public class IntentShareHelper {

    public static void shareOnTwitter(AppCompatActivity appCompatActivity, String textBody, Uri fileUri) {
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("text/plain");
        intent.setPackage("com.twitter.android");
        intent.putExtra(Intent.EXTRA_TEXT,!TextUtils.isEmpty(textBody) ? textBody : "");

        if (fileUri != null) {
            intent.putExtra(Intent.EXTRA_STREAM, fileUri);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setType("image/*");
        }

        try {
            appCompatActivity.startActivity(intent);
        } catch (android.content.ActivityNotFoundException ex) {
            ex.printStackTrace();
            showWarningDialog(appCompatActivity, appCompatActivity.getString(R.string.error_activity_not_found));
        }
    }

    public static void shareOnWhatsapp(AppCompatActivity appCompatActivity, String textBody, Uri fileUri){...}

    private static void showWarningDialog(Context context, String message) {
        new AlertDialog.Builder(context)
                .setMessage(message)
                .setNegativeButton(context.getString(R.string.close), new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                })
                .setCancelable(true)
                .create().show();
    }
}

从文件中获取开放的 ,使用下面的类:

public class UtilityFile {
    public static @Nullable Uri getUriFromFile(Context context, @Nullable File file) {
        if (file == null)
            return null;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            try {
                return FileProvider.getUriForFile(context, "com.my.package.fileprovider", file);
            } catch (Exception e) {
                e.printStackTrace();
                return null;
            }
        } else {
            return Uri.fromFile(file);
        }
    }

    // Returns the URI path to the Bitmap displayed in specified ImageView       
    public static Uri getLocalBitmapUri(Context context, ImageView imageView) {
        Drawable drawable = imageView.getDrawable();
        Bitmap bmp = null;
        if (drawable instanceof BitmapDrawable) {
            bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
        } else {
            return null;
        }
        // Store image to default external storage directory
        Uri bmpUri = null;
        try {
            // Use methods on Context to access package-specific directories on external storage.
            // This way, you don't need to request external read/write permission.
            File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
            FileOutputStream out = new FileOutputStream(file);
            bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
            out.close();

            bmpUri = getUriFromFile(context, file);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bmpUri;
    }    
}
