Get solution to change the layout of custom keyboard.

When keyboard first time load onCreateInputView() is called. After that when keyboard open onStartInputView(EditorInfo attribute, boolean restarting) called every time.

So, now layout of keyboard(Theme) have to define in onCreateInputView() Like This

public KeyboardView mInputView;
public View onCreateInputView() {

    SharedPreferences pre = getSharedPreferences("test", 1);
    int theme = pre.getInt("theme", 1);

    if(theme == 1)
    {
        this.mInputView = (KeyboardView) this.getLayoutInflater().inflate(R.layout.input, null);
    }else
    {
        this.mInputView = (KeyboardView) this.getLayoutInflater().inflate(R.layout.input_2, null);

    }
    this.mInputView.setOnKeyboardActionListener(this);
    this.mInputView.setKeyboard(this.mQwertyKeyboard);
    return this.mInputView;
}

and do this in onStartInputView

public void onStartInputView(EditorInfo attribute, boolean restarting) {
    super.onStartInputView(attribute, restarting);

    setInputView(onCreateInputView());
}
