我的问题是我想改变不同屏幕方向的框架布局高度
示例代码是
wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
Log.v("height","height"+wm.getDefaultDisplay().getHeight());
if(wm.getDefaultDisplay().getHeight() <= 427)
{
Log.v("height","111");
((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
}
else
{
((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
}
wm=(WindowManager)getSystemService(Context.WINDOW\u服务);
getWindow().addFlags(WindowManager.LayoutParams.FLAG\u保持屏幕打开);
Log.v(“height”、“height”+wm.getDefaultDisplay().getHeight());
if(wm.getDefaultDisplay().getHeight()一种方法是构建自定义视图并覆盖onLayout和onMeasure函数。在onLayout函数中,可以覆盖宽度和高度。请参见示例LabelView.java类。必须使用LinearLayout.LayoutParams(int-width、int-height、float-weight)
FrameLayout frameLayout = new FrameLayout(context);
LinearLayout.LayoutParams layPra = new LinearLayout.LayoutParams(width,height,mWeight);
layPra .gravity = Gravity.CENTER | Gravity.BOTTOM;
frameLayout .setLayoutParams(layPra );
