显示软键盘后,粘滞沉浸式模式被禁用

Question

我有一个应用程序,大多数时候需要全屏.我知道如果显示警报或显示其他窗口,则在活动窗口的顶部,会暂时删除全屏.不幸的是,当为EditText或其他东西显示软键盘时,当用户完成键盘时,不会恢复全屏沉浸式模式.

知道如何实现这一目标吗？

从Google的此示例应用中获取,您需要在活动结束时将其附加到最后一个结束括号之前:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    // When the window loses focus (e.g. the action overflow is shown),
    // cancel any pending hide action. When the window gains focus,
    // hide the system UI.
    if (hasFocus) {
        delayedHide(300);
    } else {
        mHideHandler.removeMessages(0);
    }
}

private void hideSystemUI() {
    getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE | 
        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | 
        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | 
        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | 
        View.SYSTEM_UI_FLAG_FULLSCREEN | 
        View.SYSTEM_UI_FLAG_LOW_PROFILE | 
        View.SYSTEM_UI_FLAG_IMMERSIVE
    );
}

private void showSystemUI() {
    getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE | 
        View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | 
        View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    );
}

private final Handler mHideHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        hideSystemUI();
    }
};

private void delayedHide(int delayMillis) {
    mHideHandler.removeMessages(0);
    mHideHandler.sendEmptyMessageDelayed(0, delayMillis);
}

你应该好.:)

我将此代码放在 onCreate() 观察者布局更改

getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {

        Rect rect = new Rect();
        getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
        int screenHeight = getWindow().getDecorView().getRootView().getHeight();

        int keyboardHeight = screenHeight - rect.bottom;

        if (keyboardHeight > screenHeight * 0.15) {
             setToImmersiveMode();
        }
    }
});


private void setToImmersiveMode() {
        // set to immersive
        getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }
