Change the status bar background and icon colors

By default, it's white on black. Now it's black on white
First, look at the renderings:

Screenshot_2018-01-03-19-20-27-797_com.yiban1314..png

1. Status bar background is white: set in style

<item name="colorPrimaryDark">@color/white</item>

2. Write to modify the color of the status bar icon (only black and white are known for the time being)

public class StatusBarUtil {
/**
 * Change the status bar to fully transparent
 * @param activity
 */
@TargetApi(19)
public static void transparencyBar(Activity activity){
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.setStatusBarColor(Color.TRANSPARENT);

    } else
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        Window window =activity.getWindow();
        window.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
                WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    }



}

The code above is https://www.jianshu.com/p/7f5a9969be53 Go to find it. You can go to see it
3. Specific reference column
In BaseActivity

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ActivityUtils.add(this, getClass());

    mContext = this;
    StatusBarUtil.statusBarLightMode(this);
}

4. The normal status bar has changed
The status bar has changed, but you will see that the entire activity layout will move up and fill the screen
Solution 1: add AppTheme in style

<item name="android:fitsSystemWindows">true</item>

If the code layout above is added and moved down, nothing else will be affected. Then you don't have to look down

android:fitsSystemWindows is very poor. There are many problems with the style of pop-up boxes

Solution 2: add paddingTop for each layout
LibUtils:

/**
 * Get status bar height
 * @return
 */
public static int getStatusBarHeight(Context context) {
    int result = 0;
    int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = context.getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

//Set layout distance from status bar height
public static void setLayoutPadding(Activity activity, View contentLayout) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        contentLayout
                .setPadding(contentLayout.getPaddingLeft(), getStatusBarHeight(activity) + contentLayout.getPaddingTop(),
                        contentLayout.getPaddingRight(), contentLayout.getPaddingBottom());
    }

}

Reference:

protected void onCreate(@NonNull Bundle savedInstanceState, int resId, int titleId) {
    super.onCreate(savedInstanceState);
    
    
    mContext = this;
    
    setContentView(R.layout.activity_base);
    StatusBarUtil.statusBarLightMode(this);
    LibUtils.setLayoutPadding(this,((ViewGroup)findViewById(android.R.id.content)).getChildAt(0));}

Note: after setContentView is called for LibUtils.setLayoutPadding, android.R.id.content is to obtain the root layout of each layout, and Baidu does not understand itself

We also need to consider the android version. In general, the system under 5.0 still uses the default
