Answer 1

我试图最后得到这个旋转轮我已经建立了我的轮子来获取用户的文本。我举了四个整数的例子。

 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();
}
}
