[英]libgdx make android back button act like home button
I want the back button of an android device to act like the home button when pressed (pause the app and lose focus) 我希望Android设备的后退按钮在按下时像主页按钮一样工作(暂停应用程序并失去焦点)
i have this : 我有这个 :
( Gdx.input.setInputProcessor(this);
and Gdx.input.setCatchBackKey(true);
are called) ( Gdx.input.setInputProcessor(this);
和Gdx.input.setCatchBackKey(true);
被调用)
@Override
public boolean keyDown(int keycode) {
if(keycode == Input.Keys.BACK) {
pause();
}
return false;
}
but calling the pause()
method isn't enough, what can i call to make it act like the home button ? 但是调用pause()
方法是不够的,我该如何调用使其使其像主页按钮一样?
Gdx.input.setCatchBackKey(true); // This will prevent the app from being paused.
Use Interfacing and call platform specific code by core module 通过核心模块使用接口并调用平台特定的代码
Inside core module 内部核心模块
interface PlatformService{
fun moveToStack()
}
Implement above interface in Android module 在Android模块中实现以上界面
@Override
public void moveToStack() {
this.moveTaskToBack(true);
}
Get reference of your implementation in core module and call implemented method on keyDown back button 获取核心模块中实现的参考,并在keyDown后退按钮上调用实现的方法
Gdx.input.setInputProcessor(new InputAdapter(){
@Override
public boolean keyDown(int keycode) {
if (keycode==Input.Keys.BACK){
platformService.moveToStack();
}
return super.keyDown(keycode);
}
});
call YourActivity.this.moveTaskToBack(true);
调用YourActivity.this.moveTaskToBack(true);
instead of pause();
而不是pause();
method like: 像这样的方法:
@Override
public void onBackPressed() {
this.moveTaskToBack(true);
}
Add above code in activity where you want to act back button like home button. 在您要操作后退按钮(例如主页按钮)的活动中添加以上代码。
