[工作积累] Software keyboard not shown on Activity.onCreate

    protected void onCreate (Bundle savedInstanceState)

    {

        super.onCreate(savedInstanceState);

        this.setContentView(R.layout.input);

        mInput = (EditText)findViewById(R.id.text_input);

        ...

        mInput.requestFocus();

        mInput.postDelayed(new Runnable() {

            @Override

            public void run() {

                // TODO Auto-generated method stub

                InputMethodManager keyboard =(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

                keyboard.showSoftInput(mInput, 0);

            }

        },200);

    }

 

The keyboard is hidden immediately, so showing the keyboard with some delay will solve the problem.
