【中文标题】android.view.InflateException: Binary XML file line #7: Error inflating class【英文标题】: 【发布时间】:2012-03-04 00:31:24 【问题描述】: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_
android:layout_
android:orientation="vertical" >
<org.me.TicTacToe.ui.TicTacToeBoard
android:id="@+id/game1"
android:layout_
android:layout_ />
</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 ComponentInfoorg.me.TicTacToe/org.me.TicTacToe.ui.TicTacToeActivity: org.me.TicTacToe.ui.TicTacToeBoard
如何解决?
完整的 Logcat 行:

【问题讨论】:
请向我们展示您的 logcat 的更多行。我相信崩溃的原因之前已经列出,在电路板构造函数的某个地方。 @Olegas,这是我完整的 logcat 行。我将它添加到我的第一篇文章中 【参考方案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)
【讨论】:
感谢您的回答,它确实有效!它结束了我 2 天的头痛 @Spongeboss 请接受它作为正确答案。 thnx ...它工作:) +1 要求查看“Caused by”子句。我的是“ClassNotFound Exception”,原因是我拼错了我的班级名称以上是关于android.view.InflateException: Binary XML file line #7: Error inflating class的主要内容,如果未能解决你的问题,请参考以下文章
