Android板实现双屏显示，DisplayManager和Display的使用

非常简单。

效果

1、创建分屏管理类

DisplayController

public class DisplayController {public static Display getTargetDisplay() {DisplayManager displayManager = (DisplayManager) App.getInstance().getSystemService(Context.DISPLAY_SERVICE);Display[] presentationDisplays = displayManager.getDisplays(null);LogPlus.e("###显示器数量->" + presentationDisplays.length);if (presentationDisplays.length == 0) {return null;}return presentationDisplays[presentationDisplays.length - 1];}public static void showDataView(DataViewPresentation dataViewPresentation) {dataViewPresentation.show();}public static void dissDataView(DataViewPresentation dataViewPresentation) {dataViewPresentation.dismiss();}
}

2、创建界面基类

/*** 数据展示 大屏*/
public abstract class DataViewPresentation extends Presentation {protected View layoutView;public DataViewPresentation(Context outerContext, Display display) {super(outerContext, display);}public DataViewPresentation(Context outerContext, Display display, int theme) {super(outerContext, display, theme);}@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);layoutView = getLayoutView();setContentView(layoutView);init();}protected abstract View getLayoutView();protected void init() {}
}
