Android Pop-up message

Question

I'm trying to get a pop up text box, with some disclaimer and app info at the start of my Android application's launch. Does anyone know how to implement this? Also could it read from a txt file?

Thanks

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

Your approach is very good, how to do it for 2 messages that come in handy for example toast – mehmet May 02 '17 at 13:18

You can use Dialog to create this easily

create a Dialog instance using the context

Dialog dialog = new Dialog(contex);

You can design your layout as you like.

You can add this layout to your dialog by dialog.setContentView(R.layout.popupview);//popup view is the layout you created

then you can access its content (textviews, etc.) by using findViewById method

TextView txt = (TextView)dialog.findViewById(R.id.textbox);

you can add any text here. the text can be stored in the String.xml file in res\values.

txt.setText(getString(R.string.message));

then finally show the pop up menu

dialog.show();

Use This And Call This In OnCreate Method In Which Activity You Want

public void popupMessage(){
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setMessage("No Internet Connection. Check Your Wifi Or enter code hereMobile Data.");
        alertDialogBuilder.setIcon(R.drawable.ic_no_internet);
        alertDialogBuilder.setTitle("Connection Failed");
        alertDialogBuilder.setNegativeButton("ok", new DialogInterface.OnClickListener(){

            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                Log.d("internet","Ok btn pressed");
                // add these two lines, if you wish to close the app:
                finishAffinity();
                System.exit(0);
            }
        });
        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }

Suppose you want to set a pop-up text box for clicking a button lets say bt whose id is button, then code using Toast will somewhat look like this:

Button bt;
bt = (Button) findViewById(R.id.button);
bt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {            
Toast.makeText(getApplicationContext(),"The text you want to display",Toast.LENGTH_LONG)
}

sample code show custom dialog in kotlin:

fun showDlgFurtherDetails(context: Context,title: String?, details: String?) {

    val dialog = Dialog(context)
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
    dialog.setCancelable(false)
    dialog.setContentView(R.layout.dlg_further_details)
    dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
    val lblService = dialog.findViewById(R.id.lblService) as TextView
    val lblDetails = dialog.findViewById(R.id.lblDetails) as TextView
    val imgCloseDlg = dialog.findViewById(R.id.imgCloseDlg) as ImageView

    lblService.text = title
    lblDetails.text = details
    lblDetails.movementMethod = ScrollingMovementMethod()
    lblDetails.isScrollbarFadingEnabled = false
    imgCloseDlg.setOnClickListener {
        dialog.dismiss()
    }
    dialog.show()
}
