Android Presentation双屏异显开发流程详细讲解

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        //...
    }
}

class MyPresentation(outerContext: Context, display: Display) :
    Presentation(outerContext, display) {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.dialog_normal)//绑定副屏显示的布局
    }
	//显示时调用
    override fun onStart() {
        super.onStart()
    }
    //消失时调用
    override fun onStop() {
        super.onStop()
    }
}

        myPresentation.show();
    }
}

DisplayManager mDisplayManager = (DisplayManager) getSystemService(Context.DISPLAY_SERVICE);

if (displays.length > 1) {
   //displays[0] 主屏，displays[1] 副屏
   MyPresentation myPresentation = new MyPresentation(MainActivity.this, displays[1]);
   myPresentation.show();
}
