(libgdx学习)AndroidApplicationConfiguration和 Gdx.input.isPeripheralAvailable(Peripheral.)

在libgdx中，使用AndroidApplicationConfiguration来配置app中那些设备可以使用

而是用 Gdx.input.isPeripheralAvailable(Peripheral.Compass)来查询app中那些设备可以使用

一、初始化及常用的API

//使用AndroidApplicationConfiguration给app设置特定的配置
		AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
		config.useAccelerometer = true;
		config.useCompass = true;
		initialize(new MyGame(), config);

//使用Gdx.input.isPeripheralAvailable判断一些外围设备是否可用
		boolean hardwareboard = Gdx.input.isPeripheralAvailable(Peripheral.HardwareKeyboard);
		boolean multiTouch = Gdx.input.isPeripheralAvailable(Peripheral.MultitouchScreen);
		boolean acelermetor = Gdx.input.isPeripheralAvailable(Peripheral.Accelerometer);
		boolean compass = Gdx.input.isPeripheralAvailable(Peripheral.Compass);
		
		
		System.out.println("--------->" + hardwareboard);
		System.out.println("---------->" + multiTouch);
		System.out.println("----->acelermetor: " + acelermetor);
		System.out.println("------>compass: " + compass);

二、应用举例

1、MainActivity

package com.example.groupactiontest;

import android.os.Bundle;

import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;

public class MainActivity extends AndroidApplication {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
	    
		//使用AndroidApplicationConfiguration给app设置特定的配置
		AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
		config.useAccelerometer = true;
		config.useCompass = true;
		initialize(new MyGame(), config);
		
	}
}

2、MyGame

package com.example.groupactiontest;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Input.Keys;
import com.badlogic.gdx.Input.Peripheral;
import com.badlogic.gdx.graphics.GL10;

public class MyGame implements ApplicationListener {

	@Override
	public void create() {
		
		//使用Gdx.input.isPeripheralAvailable判断一些外围设备是否可用
		boolean hardwareboard = Gdx.input.isPeripheralAvailable(Peripheral.HardwareKeyboard);
		boolean multiTouch = Gdx.input.isPeripheralAvailable(Peripheral.MultitouchScreen);
		boolean acelermetor = Gdx.input.isPeripheralAvailable(Peripheral.Accelerometer);
		boolean compass = Gdx.input.isPeripheralAvailable(Peripheral.Compass);
		
		
		System.out.println("--------->" + hardwareboard);
		System.out.println("---------->" + multiTouch);
		System.out.println("----->acelermetor: " + acelermetor);
		System.out.println("------>compass: " + compass);
		
	}

	@Override
	public void dispose() {
		// TODO Auto-generated method stub

	}

	@Override
	public void pause() {
		// TODO Auto-generated method stub

	}

	@Override
	public void render() {
		Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
		
//		if(Gdx.input.isKeyPressed(Keys.LEFT)){
//			System.out.println("你按了左键...");
//		}
		
//		if(Gdx.input.isKeyPressed(Keys.A)){//判断你是否按了A键
//			System.out.println("你按了back键..");
//		}
		
	}

	@Override
	public void resize(int arg0, int arg1) {
		// TODO Auto-generated method stub

	}

	@Override
	public void resume() {
		// TODO Auto-generated method stub

	}

}
