Question

我想使用CustomTabs库，我需要添加共享菜单项。该库只接受PendingIntent实例作为菜单项的Action。我想使用以下代码确保在没有一次和始终按钮的情况下始终向用户建议列表：

Intent shareIntent = Intent.createChooser(intent, "Choose the application to share.");

但问题是，如果我使用此选择器Intent创建PendingIntent，Chrome的CustomTabs不会为用户启动选择器：

PendingIntent pendingIntent = PendingIntent.getActivity(context,
            requestCode,
            shareIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

有没有办法将Chooser的Intent用作PendingIntent？

我无法使用以下行启动Intent，因为该库正在执行此操作并且它只接受PendingIntents：

startActivity(Intent.createChooser(i, getString()));

您可以使用广播接收器来实现此目的。

首先创建一个自定义broadcastreciever类来创建共享选择器

<强> ShareBroadcastReceiver.java

public class ShareBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    String url = intent.getDataString();
    if (url != null) {
        Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT,context.getResources().getString(R.string.chromeextra)+ url);

        Intent chooserIntent = Intent.createChooser(shareIntent, "Share url");
        chooserIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        context.startActivity(chooserIntent);
    }
}

}

然后在自定义选项卡构建器类

中设置菜单项

  String shareLabel = getString(R.string.label_action_share);
Bitmap icon = BitmapFactory.decodeResource(getResources(),
        android.R.drawable.ic_menu_share);

//Create a PendingIntent to your BroadCastReceiver implementation
Intent actionIntent = new Intent(
        this.getApplicationContext(), ShareBroadcastReceiver.class);
PendingIntent pendingIntent = 
        PendingIntent.getBroadcast(getApplicationContext(), 0, actionIntent, 0);            

//Set the pendingIntent as the action to be performed when the button is clicked.            
intentBuilder.setActionButton(icon, shareLabel, pendingIntent);

如何使用选择器中的Intent作为PendingIntent
