java - libgdx TextButton not working with json -


here menuscreen.java. class screen can set main class , display start menu.

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();     } }

i want add simple textbutton application, whenever run this, error involving skin.json file.

exception in thread "lwjgl application" com.badlogic.gdx.utils.serializationexception: error reading file: skin.json @ com.badlogic.gdx.scenes.scene2d.ui.skin.load(skin.java:97) @ com.badlogic.gdx.scenes.scene2d.ui.skin.<init>(skin.java:82) @ com.game.screens.menuscreen.<init>(menuscreen.java:21) @ com.mygdx.game.mygdxgame.create(mygdxgame.java:22) @ com.badlogic.gdx.backends.lwjgl.lwjglapplication.mainloop(lwjglapplication.java:143) @ com.badlogic.gdx.backends.lwjgl.lwjglapplication$1.run(lwjglapplication.java:120) caused by: com.badlogic.gdx.utils.serializationexception: error reading       file: skin.json @ com.badlogic.gdx.utils.json.fromjson(json.java:683) @ com.badlogic.gdx.scenes.scene2d.ui.skin.load(skin.java:95) ... 5 more caused by: com.badlogic.gdx.utils.serializationexception: error parsing file: skin.json @ com.badlogic.gdx.utils.jsonreader.parse(jsonreader.java:77) @ com.badlogic.gdx.utils.json.fromjson(json.java:681) ... 6 more caused by: com.badlogic.gdx.utils.serializationexception: error parsing json on line 1 near: : { "white": { "file": "skintest.fnt" } }, "com.badlogic.gdx.scenes.scene2d.ui.textbutton$textbuttonstyle": { "default": { "font": white } } @ com.badlogic.gdx.utils.jsonreader.parse(jsonreader.java:547) @ com.badlogic.gdx.utils.jsonreader.parse(jsonreader.java:55) @ com.badlogic.gdx.utils.jsonreader.parse(jsonreader.java:75) ... 7 more

looking @ sample skin on https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests-android/assets/data/uiskin.json

i noticed there no quotations around style classes, properties , values.

perhaps changing file following work:

{     com.badlogic.gdx.graphics.g2d.bitmapfont: {         white: { file: skintest.fnt }     },     com.badlogic.gdx.scenes.scene2d.ui.textbutton$textbuttonstyle: {         default: { font: white }     } }
