Dialog全屏显示状态栏 Dialog全屏设置修改状态栏颜色兼容刘海屏_qijingwang的博客-CSDN博客

Window dialogWindow = mDialog.getWindow();
WindowManager.LayoutParams lp = dialogWindow.getAttributes();
if(Build.VERSION.SDK_INT >= 28)
    lp.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;

dialogWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

//                View decorView = dialogWindow.getDecorView();
//                int systemUiVisibility = decorView.getSystemUiVisibility();
//                int flags = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_FULLSCREEN;
//                systemUiVisibility |= flags;
//                dialogWindow.getDecorView().setSystemUiVisibility(systemUiVisibility);
    //dialog全屏显示状态栏
    dialogWindow.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
    dialogWindow.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    dialogWindow.setStatusBarColor(Color.TRANSPARENT);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    dialogWindow.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

lp.width = LinearLayout.LayoutParams.MATCH_PARENT;

dialogWindow.setAttributes(lp);


====================================================
1. View.SYSTEM_UI_FLAG_VISIBLE：显示状态栏，Activity不全屏显示(恢复到有状态栏的正常情况)。

2. View.INVISIBLE：隐藏状态栏，同时Activity会伸展全屏显示。

3. View.SYSTEM_UI_FLAG_FULLSCREEN：Activity全屏显示，且状态栏被隐藏覆盖掉。

4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN：Activity全屏显示，但状态栏不会被隐藏覆盖，状态栏依然可见，Activity顶端布局部分会被状态遮住。

5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

6. View.SYSTEM_UI_LAYOUT_FLAGS：效果同View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION：隐藏虚拟按键(导航栏)。有些手机会用虚拟按键来代替物理按键。

8. View.SYSTEM_UI_FLAG_LOW_PROFILE：状态栏显示处于低能显示状态(low profile模式)，状态栏上一些图标显示会被隐藏。

toast 修改背景

Toast toast= Toast.makeText(context, "", Toast.LENGTH_SHORT);
View view = toast.getView();
view.setBackgroundResource(R.drawable.img_dtfzrefresh);
toast.show();

shape动态改颜色

        GradientDrawable drawable = (GradientDrawable) ContextCompat.getDrawable(context, R.drawable.shape_online_white_bg);
        drawable.setColor(Color.RED);
        llDialog.setBackground(drawable);

监听横竖屏切换

        @Override
        public void onConfigurationChanged(Configuration newConfig) {
            super.onConfigurationChanged(newConfig);
            if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
                Toast.makeText(getApplicationContext(), "横屏", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getApplicationContext(), "竖屏", Toast.LENGTH_SHORT).show();
            }
        }
