Android EditText in AlertDialog seems too wide

Question

It seems like the EditText in the image below is too wide. I assume that I have misused the SDK in some way and until convinced otherwise I am not looking for a way to specify

Answer 1

Just sorted this myself. Using an instance of AlertDialog, you can specify setView and pass in spacing parameters. This will work.

final EditText input = new EditText(this);

AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("Title");
alertDialog.setMessage("Message");
alertDialog.setView(input, 10, 0, 10, 0); // 10 spacing, left and right
alertDialog.setButton("OK", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // Clicked
    }
});
alertDialog.show();

Edit: I'm aware this question is old, but no solution was provided.

Answer 2

You can do it like this:

LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setGravity(Gravity.CENTER_HORIZONTAL);
final EditText input = new EditText(this);
input.setSingleLine(true);
layout.setPadding(10, 0, 10, 0);
input.setHint("Hint");
layout.addView(input);

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);

Moreover, setSingleLine is deprecated. You should use InputStyle.

Answer 3

Set the layout marginleft and layout marginright to 5sp. The margin sets the space around the view group. Take a look at ViewGroup.MarginLayoutParams

Answer 4

Try setting some padding on your EditText using the setPadding method. This should add a gap between the edge of the EditText and the border of the dialog. N
