I get error message when trying to run my Project. I want to create Tic Tac Toe for Android, and I use custom View below to create Tic Tac Toe board:
package org.me.TicTacToe.ui;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import android.view.MotionEvent;
import android.view.View;
public class TicTacToeBoard extends View {
private Tile[][] tile = null; //Abstract class to create tiles in Tic Tac Toe Board
int boardWidth = 3; //It mean Tic Tac Toe board is consists of 3x3 tiles
private int width;
private int height;
private Paint brush;
public TicTacToeBoard(Context context) {
super(context);
brush = new Paint();
this.brush.setARGB(255, 0, 0, 0);
this.brush.setAntiAlias(true);
this.brush.setStyle(Style.STROKE);
this.brush.setStrokeWidth(5);
width = this.getWidth();
height = this.getHeight();
initBoard();
}
@Override
protected void onDraw(Canvas canvas) {
for (int i = 0; i < tile.length; i++) {
for (int j = 0; j < tile[0].length; j++) {
tile[i][j].draw(canvas, getResources(), j, i,
(this.getWidth() + 3) / tile.length,
this.getHeight() / tile[0].length);
}
}
int xs = this.getWidth() / boardWidth;
int ys = this.getHeight() / boardWidth;
for (int i = 0; i <= boardWidth; i++) {
canvas.drawLine(xs * i, 0, xs * i, this.getHeight(), brush);
}
for (int i = 0; i <= boardWidth; i++) {
canvas.drawLine(0, ys * i, this.getWidth(), ys * i, brush);
}
super.onDraw(canvas);
}
public void initBoard(){
tile = new Tile[boardWidth][boardWidth];
int xss = width / boardWidth;
int yss = height / boardWidth;
for (int row = 0; row < boardWidth; row++) {
for (int colmn = 0; colmn < boardWidth; colmn++) {
tile[row][colmn] = new TileEmpty(xss * colmn, row * yss);
// TileEmpty is extend class from Tile.
// TileEmpty represent empty tile in Tic Tac Toe
}
}
}
}
Next, I place it in XML based activity layout like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<org.me.TicTacToe.ui.TicTacToeBoard
android:id="@+id/game1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
So I get fatal exception error in my Eclipse LogCat window:
AndroidRuntime(329): java.lang.RuntimeException: Unable to start activity ComponentInfo{org.me.TicTacToe/org.me.TicTacToe.ui.TicTacToeActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class org.me.TicTacToe.ui.TicTacToeBoard
How to fix it?

You're missing the constructor for TicTacToeBoard(Context, Attributeset)
. see this question, for example.
EDIT: It's right there in the LogCat you just posted:
Caused by: java.lang.NoSuchMethodException: TicTacToeBoard(Context,AttributeSet)
