一个Activity中添加多个Fragment导致fitsSystemWindows无效,在某个fragment中设置状态栏,背景,颜色都是自定义实现
无论是framelayout设置,还是viewpager设置,导致fitsSystemWindows无效的问题
其中你都要设置dispatchApplyWindowInsets方法
public class NewCustomViewPager extends ViewPager { private boolean isCanScroll = true; public NewCustomViewPager(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected boolean canScroll(View v, boolean checkV, int dx, int x, int y) { if (v != this && v instanceof ViewPager) { int currentItem = ((ViewPager) v).getCurrentItem(); int countItem = ((ViewPager) v).getAdapter().getCount(); return (currentItem != (countItem - 1) || dx >= 0) && (currentItem != 0 || dx <= 0); } return super.canScroll(v, checkV, dx, x, y); } @SuppressLint("ClickableViewAccessibility") @Override public boolean onTouchEvent(MotionEvent arg0) { return isCanScroll && super.onTouchEvent(arg0); } @Override public boolean onInterceptTouchEvent(MotionEvent arg0) { return isCanScroll && super.onInterceptTouchEvent(arg0); } public void setScanScroll(boolean isCanScroll) { this.isCanScroll = isCanScroll; } @TargetApi(Build.VERSION_CODES.LOLLIPOP) @Override public WindowInsets dispatchApplyWindowInsets(WindowInsets insets) { WindowInsets result = super.dispatchApplyWindowInsets(insets); if (!insets.isConsumed()) { final int count = getChildCount(); for (int i = 0; i < count; i++) result = getChildAt(i).dispatchApplyWindowInsets(insets); } return result; } @Override public void addView(View child, int index, ViewGroup.LayoutParams params) { super.addView(child, index, params); ViewCompat.requestApplyInsets(child); } }
下面是自定义FrameLayout重新它的方法
public class WindowInsetsFrameLayout extends FrameLayout { public WindowInsetsFrameLayout(Context context) { this(context, null); } public WindowInsetsFrameLayout(Context context, AttributeSet attrs) { this(context, attrs, 0); } @TargetApi(Build.VERSION_CODES.LOLLIPOP) public WindowInsetsFrameLayout(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); setOnHierarchyChangeListener(new OnHierarchyChangeListener() { @Override public void onChildViewAdded(View parent, View child) { requestApplyInsets(); } @Override public void onChildViewRemoved(View parent, View child) { } }); } @TargetApi(Build.VERSION_CODES.KITKAT_WATCH) @Override public WindowInsets onApplyWindowInsets(WindowInsets insets) { int childCount = getChildCount(); for (int index = 0; index < childCount; index++) getChildAt(index).dispatchApplyWindowInsets(insets); return insets; } }
其中因为Fragment是添加到FrameLayout这个容器的,我们给他设置一个布局层次结构改变的监听,当Fragment被添加进去的时候,通过requestApplyInsets()方法使Activity重新进行一次状态栏空间的适配,因为FrameLayout中还有其他的Fragment,我们还需要重写onApplyWindowInsets方法,对其子View进行遍历,逐个分发状态栏空间的适配事件
你可以在你想要添加activity的地方添加自定义的Theme主题
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/white</item> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item> <item name="colorPrimaryDark">@color/white</item> <item name="colorAccent">@color/status_bar</item> <item name="android:screenOrientation">portrait</item> <item name="android:windowNoTitle">true</item> </style>
在AndroidManifest.xml配置首页的theme
这是基础类
public abstract class BaseIndexAct extends AppCompatActivity { protected boolean dark = true; protected boolean isChat=false; protected AppCompatActivity activity; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); //设置布局内容 if (getLayoutId() != -1) { setContentView(getLayoutId()); } if (isChat) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { View content = ((ViewGroup) findViewById(android.R.id.content)).getChildAt(0); if (content != null) { content.setFitsSystemWindows(true); } if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { getWindow().setStatusBarColor(Color.TRANSPARENT); //去除效果不佳的半透明状态栏(如果设置了的话) getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //这里的原理是直接设置了完全透明的状态栏,并且保留了内容延伸的效果 //全屏显示设置新的状态栏:延伸内容到状态栏 getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); } } } else { StatusBarUtil.setRootViewFitsSystemWindows(this, false); //设置状态栏透明 StatusBarUtil.setTranslucentStatus(this); //一般的手机的状态栏文字和图标都是白色的, 可如果你的应用也是纯白色的, 或导致状态栏文字看不清 //所以如果你是这种情况,请使用以下代码, 设置状态使用深色文字图标风格, 否则你可以选择性注释掉这个if内容 if (!StatusBarUtil.setStatusBarDarkTheme(this, dark)) { //如果不支持设置深色风格 为了兼容总不能让状态栏白白的看不清, 于是设置一个状态栏颜色为半透明, //这样半透明+白=灰, 状态栏的文字能看得清 StatusBarUtil.setStatusBarColor(this, Color.parseColor("#ffffff")); } } activity=BaseIndexAct.this; } @TargetApi(19) public void setTranslucentStatus(boolean on) { Window win = getWindow(); WindowManager.LayoutParams winParams = win.getAttributes(); final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS; if (on) { winParams.flags |= bits; } else { winParams.flags &= ~bits; } win.setAttributes(winParams); } public abstract int getLayoutId(); }
