如何在Unity中显示类似于android的Toast消息?

里面有类似祝酒词的东西吗团结一种类似于android的操作系统,而不是GUI。在android中,用一行代码就很容易了。

public void buttonclick()
{
// Message to show
}

你可以用 Text Mathf.Lerp Color.clear 颜色,等待一段时间,然后淡出。这个 post 描述如何使用简单的 fadeInAndOut

下面是一个带有文本组件的简化toast:

void Start()
{
    showToast("Hello", 2);
}

public Text txt;

void showToast(string text,
    int duration)
{
    StartCoroutine(showToastCOR(text, duration));
}

private IEnumerator showToastCOR(string text,
    int duration)
{
    Color orginalColor = txt.color;

    txt.text = text;
    txt.enabled = true;

    //Fade in
    yield return fadeInAndOut(txt, true, 0.5f);

    //Wait for the duration
    float counter = 0;
    while (counter < duration)
    {
        counter += Time.deltaTime;
        yield return null;
    }

    //Fade out
    yield return fadeInAndOut(txt, false, 0.5f);

    txt.enabled = false;
    txt.color = orginalColor;
}

IEnumerator fadeInAndOut(Text targetText, bool fadeIn, float duration)
{
    //Set Values depending on if fadeIn or fadeOut
    float a, b;
    if (fadeIn)
    {
        a = 0f;
        b = 1f;
    }
    else
    {
        a = 1f;
        b = 0f;
    }

    Color currentColor = Color.clear;
    float counter = 0f;

    while (counter < duration)
    {
        counter += Time.deltaTime;
        float alpha = Mathf.Lerp(a, b, counter / duration);

        targetText.color = new Color(currentColor.r, currentColor.g, currentColor.b, alpha);
        yield return null;
    }
}

/// <param name="message">Message string to show in the toast.</param>
    private void _ShowAndroidToastMessage(string message)
    {
        AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject unityActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

        if (unityActivity != null)
        {
            AndroidJavaClass toastClass = new AndroidJavaClass("android.widget.Toast");
            unityActivity.Call("runOnUiThread", new AndroidJavaRunnable(() =>
            {
                AndroidJavaObject toastObject = toastClass.CallStatic<AndroidJavaObject>("makeText", unityActivity, message, 0);
                toastObject.Call("show");
            }));
        }
    }

如果不想使用该按钮,请删除btnShowHide并将函数Show()与invoke一起使用,几秒钟后将其关闭。

public class Toast : MonoBehaviour {

public Button btnShowHide;
public Text txt;
// Use this for initialization
void Start()
{ 
    //Text to be shown
    txt.enabled = false;

 //If using a button with name "Show"
 btnShowHide.GetComponentInChildren<Text>().text = "Show";

}


//Button click function

public  void Show()
{
    if (txt.isActiveAndEnabled)
    {
        txt.enabled = false;
        btnShowHide.GetComponentInChildren<Text>().text = "Show";
    }
    else
    {
        txt.enabled = true;
        btnShowHide.GetComponentInChildren<Text>().text = "Hide";
    }

}


}

或者

 public Text textfield;
// Start is called before the first frame update
void Start()
{
    textfield.text = "This is a Toast Message";
    textfield.enabled = false;
}

// Update is called once per frame
void Update()
{

}

public void TextShow()
{
    textfield.enabled = true;
    Invoke("HideText", 2f);

}

public void HideText()
{
    textfield.enabled = false;

}

public void activa_la_co_derum()
    {
        StartCoroutine("desactiva_el_radar_un_momento");
    }

    IEnumerator desactiva_el_radar_un_momento()
    {
        obj_dc.GetComponentInChildren<Text>().enabled = true;
        yield return new WaitForSeconds(1);
        obj_dc.GetComponentInChildren<Text>().enabled = false;
        yield return new WaitForSeconds(1);
        obj_dc.GetComponentInChildren<Text>().enabled = true;
        yield return new WaitForSeconds(1);
        obj_dc.GetComponentInChildren<Text>().enabled = false;
        //geimcaja_a.transform.position = new Vector3(4.57f, 0.5f, -1.34f); geimcaja_a.transform.position = new Vector3(4.57f, 0.5f, -1.34f);

        //yield return new WaitForSeconds(1);
        //Rompecabeza_triguer = false;

    }
