I want to get text from spin wheel as password. Can you please give me any example of spin wheel for getting text from it. I didn't get any good example. Thanks in advance.
解决方案
I was trying to get this spin wheel at last I have build my wheel for getting the texts from the users. I am giving a example for four integers.
package com.example.wheel;
import kankan.wheel.widget.ArrayWheelAdapter;
import kankan.wheel.widget.OnWheelChangedListener;
import kankan.wheel.widget.OnWheelScrollListener;
import kankan.wheel.widget.WheelView;
import android.R.color;
import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;
public class Wheelboxtcr extends Dialog implements
android.view.View.OnClickListener {
String wheelMenu1[] = new String[] { "0", "1", "2", "3", "4", "5", "6",
"7", "8", "9" };
/*String wheelMenu2[] = new String[] { "A", "B", "C", "D", "E", "F", "G",
"H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T",
"U", "V", "W", "X", "Y", "Z" };*/
boolean wheelScrolled = false;
public Activity c;
public Dialog d;
public Button button;
public Wheelboxtcr(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(color.transparent);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.wheellayouttcr);
button = (Button) findViewById(R.id.btn);
button.setOnClickListener(this);
initWheel1(R.id.p1);
initWheel2(R.id.p2);
initWheel3(R.id.p3);
initWheel4(R.id.p4);
}
OnWheelScrollListener scrolledListener = new OnWheelScrollListener() {
public void onScrollStarts(WheelView wheel) {
wheelScrolled = true;
}
public void onScrollEnds(WheelView wheel) {
wheelScrolled = false;
updateStatus();
}
};
// Wheel changed listener
private final OnWheelChangedListener changedListener = new OnWheelChangedListener() {
public void onChanged(WheelView wheel, int oldValue, int newValue) {
if (!wheelScrolled) {
updateStatus();
}
}
};
/**
* Updates entered PIN status
*/
private void updateStatus() {
// Main.text3.setText(wheelMenu2[getWheel(R.id.p3).getCurrentItem()]);
}
private void initWheel1(int id) {
WheelView wheel = (WheelView) findViewById(id);
wheel.setAdapter(new ArrayWheelAdapter<String>(wheelMenu1));
wheel.setVisibleItems(2);
wheel.setCurrentItem(0);
wheel.addChangingListener(changedListener);
wheel.addScrollingListener(scrolledListener);
}
private void initWheel2(int id) {
WheelView wheel = (WheelView) findViewById(id);
wheel.setAdapter(new ArrayWheelAdapter<String>(wheelMenu1));
wheel.setVisibleItems(2);
wheel.setCurrentItem(0);
wheel.addChangingListener(changedListener);
wheel.addScrollingListener(scrolledListener);
}
private void initWheel3(int id) {
WheelView wheel = (WheelView) findViewById(id);
wheel.setAdapter(new ArrayWheelAdapter<String>(wheelMenu1));
wheel.setVisibleItems(2);
wheel.setCurrentItem(0);
wheel.addChangingListener(changedListener);
wheel.addScrollingListener(scrolledListener);
}
private void initWheel4(int id) {
WheelView wheel = (WheelView) findViewById(id);
wheel.setAdapter(new ArrayWheelAdapter<String>(wheelMenu1));
wheel.setVisibleItems(2);
wheel.setCurrentItem(0);
wheel.addChangingListener(changedListener);
wheel.addScrollingListener(scrolledListener);
}
private WheelView getWheel(int id) {
return (WheelView) findViewById(id);
}
private int getWheelValue(int id) {
return getWheel(id).getCurrentItem();
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn: {
String s = wheelMenu1[getWheel(R.id.p1).getCurrentItem()]
+ wheelMenu1[getWheel(R.id.p2).getCurrentItem()]
+ wheelMenu1[getWheel(R.id.p3).getCurrentItem()]
+ wheelMenu1[getWheel(R.id.p4).getCurrentItem()]
;
Display.jno.setText(s);
break;
}
default:
break;
}
dismiss();
}
}
It's layout
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="103dp"
