您可以通过使用广播接收器来实现这一点。
首先创建一个自定义的广播接收器类来创建选择器来分享
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);
