Soft Keyboard shows up on EditText focus ONLY once

问题:

Thanks for reading.

I am facing a strange problem: My app behavior is such that when the Activity starts, I requestFocus() on an EditText and show the soft keyboard.

However, when I press the back button to dismiss the keyboard and tap the EditText I don't get the keyboard to pop up ever again. Only way out is to the start the Activity again.

Here's what my code looks like:

EditText editText = (EditText) findViewById(R.id.editText);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if(imm != null) {
            imm.toggleSoftInput(0, 0);
            imm.showSoftInput(editText, InputMethodManager.SHOW_FORCED);    
        }

And here's my XML:

<EditText android:id="@+id/editText" 
        android:layout_width="wrap_content"
        android:imeOptions="actionSearch" android:hint="Test Hint"
        android:layout_height="wrap_content" android:layout_centerHorizontal="true" 
        android:maxLength="30"> 
</EditText>

Any help would be greatly appreciated!

Thanks!

Try to open and hide inside a Runnable as,

TO OPEN

                 ettext.requestFocus();
                 ettext.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        InputMethodManager keyboard = (InputMethodManager)
                        getSystemService(Context.INPUT_METHOD_SERVICE);
                        keyboard.showSoftInput(ettext, 0);
                    }
                },200);

TO CLOSE

                    ettext.requestFocus();
                    ettext.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        InputMethodManager keyboard = (InputMethodManager)
                        getSystemService(Context.INPUT_METHOD_SERVICE);
                        keyboard.hideSoftInputFromWindow(ettext.
                                                         getWindowToken(), 0);
                    }
                },200);

You used the wrong view for showing the input window.

EditText editText = (EditText) findViewById(R.id.editText);
editText.requestFocus();
InputMethodManager imm =(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
if(imm != null) {
    imm.showSoftInput(editText, 0); 
}

try this:

final InputMethodManager imm = (InputMethodManager)EnterWordsActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm != null)
    {
        imm.toggleSoftInput(YOUE_EDTITE_TEXT.SHOW_FORCED,1);
    }
