我的智能手机有软键，我想永久隐藏在我的 APP 中。我使用下面的那个功能来隐藏软键。 

public void setFullscreen(boolean fullscreen) {
        WindowManager.LayoutParams attrs = getWindow().getAttributes();
        if (fullscreen) {
            attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
            attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
            attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
        }
        else {
            attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
            attrs.flags &= ~WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
            attrs.flags &= ~WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
        }
        getWindow().setAttributes(attrs);
        View v = this.getWindow().getDecorView();
        v.setSystemUiVisibility(View.GONE);
    }

我在 onCreate 的所有活动中调用该函数，然后像这样受保护的 void onCreate(Bundle savedInstanceState)..

    @Override
protected void onCreate(Bundle savedInstanceState)
{
    setFullscreen(true);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.myLayout);
}

问题：我正在更改活动，并且软键再次出现并隐藏。我如何防止它们出现？

我还在清单中为所有活动使用“stateHidden”

        <activity
        android:name=".myActivity"
        android:windowSoftInputMode="stateHidden" />

希望你能帮助我......非常感谢！:)

最后！这是一种解决方案。谢谢！

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_IMMERSIVE_STICKY);
}



public void setFullscreen(boolean fullscreen) {

    WindowManager.LayoutParams attrs = getWindow().getAttributes();
    if (fullscreen) {
        attrs.flags |= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
        attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
        attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
        attrs.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
        attrs.flags |= WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN;

    }
    else {
        attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
        attrs.flags &= ~WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
        attrs.flags &= ~WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
    }
    getWindow().setAttributes(attrs);
    hideSystemUI();
}
