回答1:

You have to give focus to EditText.Try

android:focusable="true"

in your EditText and it will open the soft keyboard.

Try changing your manifest to

android:windowSoftInputMode="stateVisible"

instead of

android:windowSoftInputMode="stateAlwaysVisible".

If problem persists,try opening it programatically using

InputMethodManager imm = (InputMethodManager)getSystemService(
    Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(mEditText, 0);
