When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts?
当 Activity 启动时，EditText 被聚焦，但不显示软键盘。如果我单击 EditText，则会看到软键盘。当我的 Activity 启动时，我需要设置额外的参数来显示软键盘吗？
Thanks
谢谢

Try adding this to the activities onCreate() method
尝试将此添加到活动 onCreate() 方法
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
