在我的项目中，键盘应该固定在我的 Activity 本身
In my project keyboard should fixed in my Activity itself
在我的项目中，键盘应该固定在我的 Activity 本身而不隐藏它，但在我的代码中，键盘在启动时自动可见 activity 但 问题是通过单击后退按钮键盘不可见。
所以有人可以在我的 activity
中提出修复键盘的答案吗
提前致谢
在这张图片中看到我的键盘想要固定在此 activity 中。例如计算器键盘想要在编辑文本下固定
我们有两种隐藏键盘的方法：
1:可以设置activity运行
时一直隐藏
android:windowSoftInputMode="stateHidden|stateAlwaysHidden"
2: 您可以使用java代码来隐藏键盘
public static void hideKeyboardMachine(Activity activity) {
InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
View view = activity.getCurrentFocus();
if (view != null) {
inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
希望对你有所帮助:)
