android.view.InflateException: बाइनरी एक्सएमएल फ़ाइल लाइन # 7: कक्षा

Question

को बढ़ाने में त्रुटि मुझे मेरी परियोजना चलाने की कोशिश करते समय त्रुटि संदेश मिलता है। मैं Android के लिए टिक टैक टो बनाना चाहते हैं, और मैं कस्टम दृश्य का उपयोग नीचे टिक टैक टो बोर्ड बनाने के लिए:

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 
      } 
     } 
    } 
} 

इसके बाद, मैं इस तरह XML आधारित गतिविधि लेआउट में रखें:

<?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> 

तो मैं अपने ग्रहण LogCat विंडो में घातक अपवाद त्रुटि मिलती है:

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 

इसे कैसे ठीक करें?

Answer 1

आप TicTacToeBoard(Context, Attributeset) के लिए निर्माता खो रहे हैं। उदाहरण के लिए this question देखें।

संपादित करें: यह LogCat तुम सिर्फ पोस्ट में सही नहीं है:

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