Show soft keyboard when Activity starts
提问by Al.
I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult()to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input.
我有 2 个活动，A 和 B。当 A 启动时，它检查条件，如果为真，它调用startActivityForResult()启动 B。B 只接受文本输入，因此当 B 启动时软键盘自动弹出是有意义的。当活动开始时，EditText 已经获得焦点并准备好输入。
The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible"set in the manifest under the <activity>tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show.
问题是键盘永远不会出现，即使windowSoftInputMode="stateAlwaysVisible"在<activity>B 标签下的清单中设置。我也尝试将值设置为stateVisible。由于它不会自动显示，我必须点击 EditText 使其显示。
Anyone know what the solution might be?
任何人都知道解决方案可能是什么？

I have got two way.
我有两种方法。
Method 1.Use the following code inside the OnCreate method
方法一、在OnCreate方法中使用如下代码
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
It will prevent popping up keyboard unless you click.
除非您单击，否则它将防止弹出键盘。
or
或者
Method 2You can move away the focus on other view like TextView by using "requestfocus" in the xml.
方法 2您可以通过在 xml 中使用“requestfocus”将焦点移到 TextView 等其他视图上。
<TextView
android:id="@+id/year_birth_day"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="1991">
<requestFocus />
</TextView>
Method 3( I think it should be avoidable) Using the following code in the manifest-
方法3（我认为应该可以避免）在清单中使用以下代码-
android:windowSoftInputMode="stateVisible"

Try showing the keyboard with some delay. Something similar to this:
尝试延迟显示键盘。类似的东西：
public void onResume() {
super.onResume();
TimerTask tt = new TimerTask() {
@Override
public void run() {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourTextBox, InputMethodManager.SHOW_IMPLICIT);
}
};
final Timer timer = new Timer();
timer.schedule(tt, 200);
}

If you're using an emulator, you have to turn the hard keyboard off in order for the soft keyboard to show.
如果您使用的是模拟器，则必须关闭硬键盘才能显示软键盘。

Major Attention Required!
需要重点关注！
android:windowSoftInputMode="stateVisible|adjustPan"This alone won't work to show keyboard on activity start.
android:windowSoftInputMode="stateVisible|adjustPan"仅此一项无法在活动开始时显示键盘。
You also need to explicitly add this into your class
您还需要将其显式添加到您的班级中
editTextXYZ.requestFocus()
val imm: InputMethodManager =
getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.showSoftInput(editTextXYZ, InputMethodManager.SHOW_IMPLICIT)
