android.view.InflateException: Binary XML file line #7: Error inflating class

Question

尝试运行我的项目时收到错误消息。我想为 Android 创建井字游戏，我使用下面的自定义视图来创建井字游戏板：

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
            }
        }
    }
}

接下来，我将它放在基于 XML 的活动布局中，如下所示：

<?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>

所以我的 Eclipse LogCat 窗口中出现致命异常错误：

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

如何解决？

Answer 1

您缺少TicTacToeBoard(Context, Attributeset) 的构造函数。例如，参见this question。

编辑： 它就在您刚刚发布的 LogCat 中：

  Caused by: java.lang.NoSuchMethodException: TicTacToeBoard(Context,AttributeSet)
