How can I convert a key code into a char or string?

How to convert the keycode into char or string??

Here is the example code:

public boolean onKey(View v, int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub
    //Log.d("EditText", "It's Working...!" + event.getAction());
    if (event.getAction() == 0) {
        switch (v.getId()) {
        case R.id.editText1:
            Log.d("EditText", "In editText1");
            if (text1.length() == 3)
            {
                text2.setText();
                text2.requestFocus();

            }
            break;

        case R.id.editText2:
            Log.d("EditText", "In editText2");
            if (text2.length() == 0)
                text1.开发者_C百科requestFocus();
            break;
        }
    }

    return false;
}

char unicodeChar = (char)event.getUnicodeChar();

---

Use event.getNumber().

---

If you don't have a KeyEvent object you can use this on the keycode :

public void onKey(int primaryCode, int[] keyCodes) {
     char c = Character.toChars(primaryCode)[0];
}

---

Tod answer is almost complete, but when you want to settext of an edittext with this eventcode you should to add a little thing:

sample_et.setText((char)event.getUnicodeChar()+"");

---

If you want to send a key from one control to another (for instance, from RecylerView to EditText inside it), you can use this:

editText.dispatchKeyEvent(KeyEvent(0, 0, KeyEvent.ACTION_DOWN, keyCode, 0))
editText.dispatchKeyEvent(KeyEvent(0, 0, KeyEvent.ACTION_UP, keyCode, 0))

---

Try this..

String s="";

@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
    EditText t=(EditText)v;
    s=t.getText();  
    return false;
}

Use

String.fromCharCode();

String.fromCharCode(65,66,67) returns ABC.
