Show toast widget underneath a view


For those who helped me out earlier regarding this project, thank you very much! My code no longer has any problems, and I made extra tweaks. Now that the app is actually robust now, I want to do one more thing.

See screenshot of the layout here.

Normally, the toast view appears at the bottom center of the screen. I want to make it appear just below (8dp) the Submit button once OnClick is called. How can I accomplish this.

See my updated complete project here.

package com.lookjohn.guessnumber;

import java.util.Random;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
Random random; 
Button button;
EditText text;

int input; 
int MIN, MAX;
int comp; 
int guesses;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    random = new Random();
    button = (Button)findViewById(R.id.button1);
    text = (EditText)findViewById(R.id.editText1);

    MIN = 1;
    MAX = 100;
    comp = random.nextInt(MAX - MIN + 1) + MIN; // Generate random number between 1 and 100.
    guesses = 0;

    button.setOnClickListener(myhandler1);
}

View.OnClickListener myhandler1 = new View.OnClickListener() {

    public void onClick(View v) {

        // Implemented max number of guesses, detect 
        // number of guesses and return from the method.

        String value = text.getText().toString(); // Get value from input from editTextView

        // If user submits an empty EditText, return to prevent a crash.
        if (value.isEmpty()) {
            Toast.makeText(MainActivity.this, "You must enter a guess!", Toast.LENGTH_SHORT);
            return;
        }

        input = Integer.parseInt(value); // Turn string into integer
        guesses++;
        if (input > 100) {
            Toast.makeText(MainActivity.this, 
                "That number is greater than 100. Not Valid!", 
                Toast.LENGTH_SHORT).show();
                return;
            }

        else if (input < comp)
            Toast.makeText(MainActivity.this, 
                "Your number is too small.", 
                Toast.LENGTH_SHORT).show();
        else if (input > comp) 
            Toast.makeText(MainActivity.this, 
                "Your number is too big.", 
                Toast.LENGTH_SHORT).show();
        else
            Toast.makeText(MainActivity.this, 
                "Good job! The answer was " + comp + ".\n" +
                "You made " + guesses + " guesses.\n" +
                "Restart the app to try again.", 
                Toast.LENGTH_LONG).show();
    }
};

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

Solution

  • From what I learned, this is the best I came up with for the program. Doing this puts the Toast message in the center of the phone.

    if(input > 100) {   
                Toast toast = Toast.makeText(MainActivity.this, 
                    R.string.over_guess, 
                    Toast.LENGTH_SHORT);
                toast.setGravity(Gravity.CENTER, 0, 0); 
                toast.show();   
                return;
                }
            else if(input < comp) {
                Toast toast = Toast.makeText(MainActivity.this, 
                    getString(R.string.guess_low, input), 
                    Toast.LENGTH_SHORT);
                toast.setGravity(Gravity.CENTER, 0, 0); 
                toast.show();
            }
            else if(input > comp) {
                Toast toast = Toast.makeText(MainActivity.this, 
                    getString(R.string.guess_high, input), 
                    Toast.LENGTH_SHORT);
                toast.setGravity(Gravity.CENTER, 0, 0); 
                toast.show();
            }
            else {
                Toast toast = Toast.makeText(MainActivity.this, 
                    getString(R.string.correct, comp, guesses), 
                    Toast.LENGTH_LONG);
                toast.setGravity(Gravity.CENTER, 0, 0); 
                toast.show();
            }
