全面屏手機存在底部虛擬鍵盤遮擋dailog問題晕换，解決方式是在dialog彈出時隱藏虛擬鍵盤窖式，dialog消失dismiss時顯示虛擬鍵盤：
隱藏虛擬鍵盤:

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
        getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
            @Override
            public void onSystemUiVisibilityChange(int visibility) {
                int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
                        //布局位于狀態(tài)欄下方
                        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
                        //全屏
//                        View.SYSTEM_UI_FLAG_FULLSCREEN |
                        //隱藏導(dǎo)航欄
                        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
                        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
                if (Build.VERSION.SDK_INT >= 19) {
                    uiOptions |= 0x00001000;
                } else {
                    uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;
                }
                getWindow().getDecorView().setSystemUiVisibility(uiOptions);
            }
        });

顯示虛擬鍵盤：

        setOnDismissListener(new OnDismissListener() {
            @Override
            public void onDismiss(DialogInterface dialog) {
                getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
                getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
                    @Override
                    public void onSystemUiVisibilityChange(int visibility) {
                        int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
                                //布局位于狀態(tài)欄下方
                                View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
                                //全屏
//                                View.SYSTEM_UI_FLAG_FULLSCREEN |
                                //隱藏導(dǎo)航欄
                                View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
                                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN;
                        if (Build.VERSION.SDK_INT >= 19) {
                            uiOptions |= 0x00001000;
                        } else {
                            uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE;
                        }
                        getWindow().getDecorView().setSystemUiVisibility(uiOptions);
                    }
                });
            }
        });

或者修改style

    <style name="Dialog_Comment">
        <item name="android:background">@color/transparent</item>
        <item name="android:windowBackground">@color/transparent</item>
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:navigationBarColor">@color/transparent</item>
        <!--<item name="android:windowIsFloating">true</item>-->
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:gravity">bottom</item>
        <item name="android:windowAnimationStyle">@style/popwindow_anim_style</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:interpolator">@android:anim/bounce_interpolator</item>
        <item name="android:backgroundDimEnabled">false</item>
    </style>
