android.view.InflateException: Dòng tệp XML nhị phân # 7: Lỗi khi tăng cấp lớp

Question

Tôi nhận được thông báo lỗi khi cố gắng chạy Dự án của mình. Tôi muốn tạo ra Tic Tac Toe cho Android, và tôi sử dụng tùy chỉnh Xem dưới đây để tạo 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 
      } 
     } 
    } 
} 

Tiếp theo, tôi đặt nó trong cách bố trí hoạt động dựa trên XML như thế này:

<?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> 

Vì vậy, tôi nhận được lỗi ngoại lệ nghiêm trọng trong cửa sổ Eclipse LogCat của tôi:

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 

Cách khắc phục?

Answer 1

Bạn đang thiếu các nhà xây dựng cho TicTacToeBoard(Context, Attributeset). xem ví dụ this question.

EDIT: Đó là ngay trong LogCat bạn chỉ cần gửi:

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