[英]android - Transparent Navigation Bar but not Status Bar
我不确定是否可以,但是我试图使导航栏透明而不使状态栏透明。 稍后的原因是我有一个工具栏,否则它会在状态栏后面绘制。
现在,我正在使用一个falseStatusBar布局,该布局显示在状态栏之前,因此对用户而言一切都很好:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
Window window = getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
//now the status bar is transparent too, which we have to fix
//first we get status bar height
int statusBarHeight = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
//then we get the full width
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int screenWidth = size.x;
//then we set that height to the fake item in the layout
LinearLayout fakeStatusBar = findViewById(R.id.fakeStatusBar);
ViewGroup.LayoutParams params = fakeStatusBar.getLayoutParams();
params.height = statusBarHeight;
params.width = screenWidth;
fakeStatusBar.setLayoutParams(params);
唯一的问题是,在进行多任务处理时,缩略图看起来不佳,因为工具栏不在应有的位置。
并不是我想要的,但我发现了使用半透明导航栏的解决方法。 最终代码如下所示:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
//set navigation bar translucent
Window window = getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
//now the status bar is translucent too, which we have to fix
//first we get status bar height
int statusBarHeight = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
//then set it as top padding for the main layout
ConstraintLayout mainLayout = (ConstraintLayout) findViewById(R.id.mainLayout);
mainLayout.setPadding(0,statusBarHeight,0,0);
}
将顶部填充添加到活动的主布局的位置。
如果有人知道如何使用透明导航栏执行类似操作,那就太好了,但否则我对我的解决方案感到满意。
