Hello,
Is it possible to open numeric keyboard on Android phone ?
I use openKeyboard() in Android mode, it open text keyboard.
I put android:reqKeyboardType=“twelvekey” in AndroidManifest.xml but always the text keyboard appears.
Is there a method to do that ?
Thanks by advance
Yves
Hi
Full function virtual keyboard
One more
import android.view.inputmethod.InputMethodManager;
import android.content.Context;
void toggleKeyboard() {
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, 0);
}
/*
* This example includes a function to toggle (show/hide) the software keyboard
* and illustrates how to edit a string using the keyboard.
*
* Pressing delete/backspace will delete one character; if none are left it will hide the keyboard.
* Pressing return will hide the keyboard.
*
* In Android, you can also use the back arrow to close the keyboard. As this sketch doesn't explicitly
* open or close the keyboard (just toggles its state), you may come to an inconsistent behaviour.
*
* The function is in a separate tab, so it may easily be copied to another sketch.
*
* NOTE: this sketch does not work well with autocomplete, which should be off by default.

if (keyPress == ' ' || keyPress == '-' || keyPress == '_' || keyPress == '.' || keyPress == ',' || keyPress == ';' || keyPress == '?' || keyPress == '!' || keyPress == '\'') return true;

}
Thanks for reply, but toggleKeyboard(), like openKeyboard() open it only in text mode not in numeric mode.
I see something with EditText but i don’t understand how to use EditText in Processing.
Thanks
You are correct that you need to use EditText to get a numeric keypad. This may be accomplished by adding a single line to your EditText code:
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
Example code is shown below:
Reference:https://stackoverflow.com/questions/13817521/how-do-you-set-the-edittext-keyboard-to-only-consist-of-numbers-on-android
import android.app.Activity;
import android.content.Context;
import android.view.View;
import android.widget.EditText;
import android.widget.RelativeLayout;
import android.view.ViewGroup.LayoutParams;
import android.text.Editable;
import android.view.inputmethod.InputMethodManager;
import android.view.KeyEvent;
import android.view.InputEvent;
import android.widget.FrameLayout;
import android.R;
import android.text.InputType;
color BLUE = color(64,124,188);
color LTGRAY = color(185,180,180);
color YELLOW = color(245,250,13);
color RED = color(255,0,0);
color BLACK = color(0,0,0);
color WHITE = color(255,255,255);
color GREEN = color(32,175,47);
color ORANGE = color(237, 147, 29);
Activity activity;
Context ctx;
EditText editText;
void editText(int x, int y, int w, int h, color bkgrnd, color txtColor, float txtSize) {
editText = new EditText(ctx);
editText.setLayoutParams (new RelativeLayout.LayoutParams (RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT));
editText.setTextColor(txtColor);
editText.setBackgroundColor(bkgrnd);
editText.getLayoutParams().width = w;
editText.getLayoutParams().height = h;
editText.setX(x);
editText.setY(y);
editText.setTextSize(txtSize);
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
editText.setOnKeyListener(new View.OnKeyListener() {
@ Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN && event.getKeyCode()== KeyEvent.KEYCODE_ENTER) {
InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
String value = editText.getText().toString();
println(value);
return true;
}
return false;
}
}
);
FrameLayout layout = (FrameLayout)activity.findViewById(R.id.content);
layout.addView(editText);
}
void setup() {
fullScreen();
orientation(LANDSCAPE);
background(BLUE);
activity = this.getActivity();
ctx = activity.getApplicationContext();
runOnUiThread(new Runnable() {
void run() {
editText(300, 300, 800, 100, ORANGE, BLACK, 28.0);
}
}
);
}
void draw() {
}
Thanks a lot Svan, it works fine.
I didn’t know i had to import so much librairies, it is like include in C .
It works but i don’t know how get the string from the editText ?
Cheers
Yves
See revision. You may not need all those imports; depends on what you are trying to do. Experiment to see which ones you don’t need.
Thanks for your replies,
I read the return of editText by
if(editText.getText().toString().equals("XXXXX"))
I put the editText declaration in second folder so i use it in first folder by
runOnUiThread(new Runnable() {
void run() {
editText(40, 40, 640, 100, WHITE, BLACK, 28);
}
}
);
editText.setVisibility(View.INVISIBLE);
at startup and visible when needed.
It works fine, but seems complicated by comparaison to traditionnal C language.
