copied!<p>In the hello android book there is a Sudoku solution. I wanted to create a message at the end that displays a dialog saying congratulations. I have a method to check if there are any empty squareds left and I call that in another method that checks if the last input was a valid entry for the square</p> <pre><code>/****** Check to see if the game is complete **/ public boolean isSolved() { for (int element : puzzle) { if (element == 0) return false; } return true; } /** Change the tile only if it's a valid move */ protected boolean setTileIfValid(int x, int y, int value) { int tiles[] = getUsedTiles(x, y); if (value != 0) { for (int tile : tiles) { if (tile == value) return false; } } setTile(x, y, value); calculateUsedTiles(); //check if the game is complete after each valid move if (isSolved() == true) { Intent i = new Intent(this, Congratulations.class); startActivity(i);} else { return false; } return true; } </code></pre> <p>For some reason when i enter a tile before the game is complete the whole screen shakes from side to side. This did not do this before I entered the checking of the game. Why and where is it doing this?</p> <p>Congratulatons.xml <code><?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dip" > <TextView android:id="@+id/about_content" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/congratulations_text" /> </ScrollView> </code> Congratulations.java</p> <pre><code>package com.example.sudoku; import android.app.Activity; import android.os.Bundle; public class Congratulations extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.congratulations); } } </code></pre>
