Solution

  • Use this code in XML to allow numbers only in Edit Text:

    <EditText android:id="@+id/edit_text_id"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:inputType="numbers" />

    To control the text values entered in that EditText:

    edittext.addTextChangedListener(new TextWatcher(){
    public void afterTextChanged(Editable s) {}

    public void beforeTextChanged(CharSequence s, int start, int count, int after){}

    public void onTextChanged(CharSequence s, int start, int before, int count){
        String strEnteredVal = edittext.getText().toString();

        if(!strEnteredVal.equals("")){
        int num=Integer.parseInt(strEnteredVal);
        if(num<60){
         edittext.setText(""+num);
        }else{
         edittext.setText("");
        }
    }

});
