android强制键盘可见
我的函数，从 onResume() 运行不会导致键盘出现。
我做错了吗？
private void showKeyboard() {
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(txtSearch, InputMethodManager.SHOW_FORCED);
txtSearch.requestFocus();}
My function, run from the onResume() does not cause the keyboard to appear.
Am I doing it wrong?
private void showKeyboard() {
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(txtSearch, InputMethodManager.SHOW_FORCED);
txtSearch.requestFocus();}

软键盘有时会很棘手。我相信最后一行 txtSearch.requestFocus() 是不必要的，实际上可能会把事情搞砸。通过告诉键盘在 txtSearch 上显示 SHOW_FORCED，您已经告诉它获得焦点。
The soft keyboard can be tricky sometimes. I belive the last line,
txtSearch.requestFocus()is unnecessary, and could actually be screwing things up. By telling the keyboard to SHOW_FORCED on txtSearch you are already telling it to have focus.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
可能会帮助你。
请注意，有些 Android 设备带有硬件键盘。
eG GoogleTV 设备通常没有触摸屏，但有硬件键盘。
有些甚至模仿触摸屏。
如果您在模拟器中进行开发，这是相关的：

“在实验时，我实际上并没有得到我想要的东西，直到我意识到我应该有一个模拟器没有硬件键盘的设备：”
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
may help you.
Note that there are Android devices with hardware-keyboards out there.
e.G. GoogleTV devices often have no touchscreen but a hardware-keyboard.
Some are even emulating the touchscreen.
This is relevant if you are developing in an emulator:
