使用Android上的Kotlin共享意图文本

我想在我的 cardView 中使用Kotlin共享意图，但是Kotlin中的代码中的最后一行存在问题代码

 val shareIntent = Intent()
            shareIntent.action = Intent.ACTION_SEND
            shareIntent.putExtra(Intent.EXTRA_STREAM, "ali")
            shareIntent.type = "text/plain"
            startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)))

这是代码中的问题

startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)))

请帮助我

适配器完整代码

class MyAdapter(context: Context, listItem: ArrayList<com.EliteTeam.comedytaste.Model.Movie>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() {
var Context = context
var movieList = listItem;
var layoutInflator = LayoutInflater.from(context)
override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): MyViewHolder {
    var inflateView = layoutInflator.inflate(R.layout.single_item, parent, false)
    return MyViewHolder(inflateView)
}
override fun onBindViewHolder(holder: MyViewHolder?, position: Int) {
    holder?.moviewTitle?.text = movieList[position].name
    holder?.movieDescription!!.text=   movieList[position].description
    //holder!!.cardImageView!!.background=   movieList[position].image
    holder?.onclick(Context, position)
    holder!!.cardImageView.setBackgroundResource(movieList[position].image)
}
override fun getItemCount(): Int {
    return movieList.size
}
class MyViewHolder(itemView: View?) : RecyclerView.ViewHolder(itemView) {
    var moviewTitle: TextView = itemView?.findViewById(R.id.movieTitleTextView)!!
    var movieDescription: TextView = itemView!!.findViewById(R.id.movieDescriptionTextView)
    var cardImageView: CardView = itemView!!.findViewById(R.id.imageCard)
    var share: ImageButton = itemView!!.findViewById(R.id.share)
    fun onclick(context: Context, position: Int) {
        cardImageView.setOnClickListener {
    }
       share.setOnClickListener {
           val shareIntent = Intent()
         shareIntent.action = Intent.ACTION_SEND
           shareIntent.putExtra(Intent.EXTRA_TEXT, "ali")
          shareIntent.type = "text/plain"

           startActivity(Intent.createChooser(shareIntent,"send to"))
}} }}

尝试以下操作： - 使用 Intent.EXTRA_STREAM 仅在您必须发送二进制数据（如images）时，如果要发送文本 Intent.EXTRA_TEXT

    val shareIntent = Intent()
    shareIntent.action = Intent.ACTION_SEND
    shareIntent.type="text/plain"
    shareIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
    startActivity(Intent.createChooser(shareIntent,getString(R.string.send_to)))

如果在适配器中使用此代码，则最后一行应该是 context.startActivity(Intent.createChooser(shareIntent,getString(R.string.send_to)))

在活动中共享文本

    val intent = Intent(Intent.ACTION_SEND)
    intent.putExtra(Intent.EXTRA_TEXT, "shareTextHere")
    intent.type = "text/plain"
    startActivity(Intent.createChooser(intent, "Share Via"))

在适配器中共享文本

    val intent = Intent(Intent.ACTION_SEND)
    intent.putExtra(Intent.EXTRA_TEXT, "shareTextHere")
    intent.type = "text/plain"
    context.startActivity(Intent.createChooser(intent, "Share Via"))

您可以直接使用这些功能：

fun showSharingDialogAsKotlin(text: String) {
    val intent = Intent()
    intent.action = Intent.ACTION_SEND
    intent.type = "text/plain"
    intent.putExtra(Intent.EXTRA_TEXT, text)
    startActivity(Intent.createChooser(intent, "Share with:"))
}

另外，如果您想显示图像，并且是否有链接：

fun showSharingDialogAsKotlinWithURL(text: String, url: String) {
    val intent = Intent()
    intent.action = Intent.ACTION_SEND
    intent.type = "text/plain"
    intent.putExtra(Intent.EXTRA_TEXT, "$text: $url")
    startActivity(Intent.createChooser(intent, "Share with:"))
}

只使用

context.startActivity

设置

startActivity

您当然可以转到"开始活动"的定义并查看过载，因为您没有传递可接受的参数之一。

我喜欢做的事情，以便在整个地方都有导航代码，就是创建这样的意图：

public class IntentFactory {
/**
 *
 * @param context
 * @return intent
 */
public static Intent getLoginIntent(Context context, boolean launchedFromNotification, boolean isApproveNotify, String idOfDetailToOpen, NewsModel notificationModel){
    Intent intent = new Intent(context, LoginActivity.class);
    intent.putExtra(Globals.INTENT_KEYS.KEY_FROM_BADGE_ACCESS, launchedFromNotification);
    intent.putExtra(Globals.INTENT_KEYS.KEY_ID_OF_DETAIL_TO_OPEN, idOfDetailToOpen);
    intent.putExtra(Globals.INTENT_KEYS.KEY_IS_APPROVE_NOTIFY, isApproveNotify);
    intent.putExtra(Globals.INTENT_KEYS.KEY_ALERT_NOTIFICATION_FOR_APPROVAL, notificationModel);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
    return intent;
}
/**
 *
 * @param filePath
 * @param subject
 * @param body
 * @return
 */
public static Intent getSendImageIntent(String filePath, String subject, String body){
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("image/jpg");
    intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + filePath));
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, body);
    return Intent.createChooser(intent, "Share File");
}
/**
 *
 * @param toEmailAddresses
 * @param subject
 * @param body
 * @param uris
 * @return
 */
public static Intent getEmailIntent(String[] toEmailAddresses, String subject, String body, ArrayList<Uri> uris) {
    Intent intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_EMAIL, toEmailAddresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, body);
    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    if(uris != null) {
        intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    }
    return Intent.createChooser(intent, "Send mail...");
}
/**
 * Used to launch to app details screen for toggling of permissions or other things
 * @param context
 * @return
 */
public static Intent getShowAppDetailSettingsIntent(Context context){
    Intent intent = new Intent();
    intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    intent.addCategory(Intent.CATEGORY_DEFAULT);
    intent.setData(Uri.parse("package:" + context.getPackageName()));
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
    return intent;
}
}

然后，您可以使用

的起始性调用轻松管理

      String email = SharedPreferencesManager.getInstance(getContext()).getSecuredPreference(REMEMBER_ME_USER_KEY);
    String subject = getString(R.string.message) + " " + model.getFirstName() + " " + model.getLastName();
    String body = getString(R.string.subject) + model.getFirstName() + " " + model.getLastName() + "n" + model.getShootKeyUrl();
    startActivity(IntentFactory.getEmailIntent(new String[]{email}, subject, body, null));

因此，如果您对齐适当的参数，您将很好，但是我仍然建议提取它以便于这样更新到这样的工厂。
