libgdx TextButton不能用於json

這是我的MenuScreen.java。這是一個可以從主類設置屏幕的類，並將顯示一個開始菜單。libgdx TextButton不能用於json

package com.game.screens; 

import com.badlogic.gdx.Game; 
import com.badlogic.gdx.Gdx; 
import com.badlogic.gdx.Screen; 
import com.badlogic.gdx.graphics.GL20; 
import com.badlogic.gdx.graphics.g2d.BitmapFont; 
import com.badlogic.gdx.graphics.g2d.TextureAtlas; 
import com.badlogic.gdx.scenes.scene2d.Stage; 
import com.badlogic.gdx.scenes.scene2d.ui.Skin; 
import com.badlogic.gdx.scenes.scene2d.ui.Table; 
import com.badlogic.gdx.scenes.scene2d.ui.TextButton; 
import com.badlogic.gdx.scenes.scene2d.ui.TextField; 

public class MenuScreen implements Screen 
{ 
    private Stage stage = new Stage(); 
    private Table table = new Table(); 

    private Skin skin = new Skin(Gdx.files.internal("skin.json"), 
     new TextureAtlas(Gdx.files.internal("testingStuff.pack"))); 

    private TextButton buttonPlay = new TextButton("Play", skin), 
     buttonExit = new TextButton("Exit", skin); 


    @Override 
    public void show() 
    { 
     table.add(buttonPlay).row(); 
     table.add(buttonExit).row(); 

     table.setFillParent(true); 
     stage.addActor(table); 

     Gdx.input.setInputProcessor(stage); 
    } 

    @Override 
    public void render(float delta) 
    { 
     Gdx.gl.glClearColor(0, 0, 0, 1); 
     Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); 
     stage.act(); 
     stage.draw(); 
    } 

    @Override 
    public void resize(int width, int height) 
    { 

    } 

    @Override 
    public void pause() 
    { 

    } 

    @Override 
    public void resume() 
    { 

    } 

    @Override 
    public void hide() 
    { 
     dispose(); 
    } 

    @Override 
    public void dispose() 
    { 
     stage.dispose(); 
     skin.dispose(); 
    } 
}

我想一個簡單的TEXT按鈕添加到我的應用程序，但每當我運行它，我得到這個錯誤涉及skin.json文件。

上https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests-android/assets/data/uiskin.json

我注意到周圍有風格類，屬性和值沒有報價在研究樣本的皮膚。

也許改變你的文件，像下面將工作：

{ 
    com.badlogic.gdx.graphics.g2d.BitmapFont: { 
     white: { file: skinTest.fnt } 
    }, 
    com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle: { 
     default: { font: white } 
    } 
}

這是報價，謝謝！ – mcjcloud

似乎與您的*.json文件有問題。它應該看起來像這樣：

{ 
    "com.badlogic.gdx.graphics.g2d.BitmapFont": { 
     "white": { "file": "skinTest.fnt" } 
    }, 
    "com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle": { 
     "default": { "font": white } 
    } 
}

它工作正常，我的*.fnt文件。也許你的*.fnt文件路徑是錯誤的。正常情況下，它應該位於android/assets/skinTest.fnt。如果您正在桌面上測試應用程序，則還應將工作目錄設置爲assets文件夾。（我使用過Android Studio）
