將圖像添加到吐司？

是，您可以使用的setView（）方法，使用這種方法，你可以自定義吐司按照您的要求添加的ImageView或任何視圖到Toast通知。

在這裏我創建了一個自定義佈局文件，將其充氣到Toast通知中，然後我通過使用setView（）方法在Toast通知中使用了此佈局。

cust_toast_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/relativeLayout1" 
    android:background="@android:color/white"> 

    <TextView 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:id="@+id/textView1" android:layout_height="wrap_content" 
     android:layout_width="fill_parent" 
     android:text="PM is here" 
     android:gravity="center" 
     android:textColor="@android:color/black"> 
    </TextView> 

    <ImageView 
     android:layout_height="wrap_content" 
     android:layout_width="fill_parent" 
     android:src="@drawable/new_logo" 
     android:layout_below="@+id/textView1" 
     android:layout_margin="5dip" 
     android:id="@+id/imageView1"> 
    </ImageView> 

    <TextView 
     android:id="@+id/textView2" 
     android:layout_height="wrap_content" 
     android:layout_width="fill_parent" 
     android:text="This is the demo of Custom Toast Notification" 
     android:gravity="center" 
     android:layout_below="@+id/imageView1" 
     android:textColor="@android:color/black"> 
    </TextView> 

</RelativeLayout>

CustomToastDemoActivity.java

LayoutInflater inflater = getLayoutInflater(); 
    View view = inflater.inflate(R.layout.cust_toast_layout, 
            (ViewGroup) findViewById(R.id.relativeLayout1)); 

    Toast toast = new Toast(this); 
    toast.setView(view); 
    toast.show();

您可以編程方式創建任何視圖（因爲我假設您問的是如何在不使用LayoutInflater的情況下執行此操作）並在您所做的Toast上調用setView。

//Create a view here 
    LinearLayout v = new LinearLayout(this); 
    //populate layout with your image and text or whatever you want to put in here 

    Toast toast = new Toast(getApplicationContext()); 
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); 
    toast.setDuration(Toast.LENGTH_LONG); 
    toast.setView(v); 
    toast.show();

總有創建一個自定義佈局的可能性。有一個我不喜歡的事實：它打破了系統默認的Toast UI。這可能在不同的平臺和實現上有所不同。有沒有簡單的方法來使用系統默認資源，所以我決定砍掉敬酒，並強制一個圖像。

提示：你可以得到這樣的默認資源：
Toast.makeToast(context, "", 0).getView().getBackground()

這裏將在吐司消息的前面顯示圖像的幫手： Helper.makeImageToast(context, R.drawable.my_image, "Toast with image", Toast.LENGTH_SHORT).show()

我用這表明成功，信息或錯誤。使舉杯信息更好，更具表現力......

（值得一提的是，這樣的事實，內部敬酒使用LinearLayout所以不是制度和實施獨立的黑客基地。見註釋）。

public static Toast makeImageToast(Context context, int imageResId, CharSequence text, int length) { 
    Toast toast = Toast.makeText(context, text, length); 

    View rootView = toast.getView(); 
    LinearLayout linearLayout = null; 
    View messageTextView = null; 

    // check (expected) toast layout 
    if (rootView instanceof LinearLayout) { 
     linearLayout = (LinearLayout) rootView; 

     if (linearLayout.getChildCount() == 1) { 
      View child = linearLayout.getChildAt(0); 

      if (child instanceof TextView) { 
       messageTextView = (TextView) child; 
      } 
     } 
    } 

    // cancel modification because toast layout is not what we expected 
    if (linearLayout == null || messageTextView == null) { 
     return toast; 
    } 

    ViewGroup.LayoutParams textParams = messageTextView.getLayoutParams(); 
    ((LinearLayout.LayoutParams) textParams).gravity = Gravity.CENTER_VERTICAL; 

    // convert dip dimension 
    float density = context.getResources().getDisplayMetrics().density; 
    int imageSize = (int) (density * 25 + 0.5f); 
    int imageMargin = (int) (density * 15 + 0.5f); 

    // setup image view layout parameters 
    LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(imageSize, imageSize); 
    imageParams.setMargins(0, 0, imageMargin, 0); 
    imageParams.gravity = Gravity.CENTER_VERTICAL; 

    // setup image view 
    ImageView imageView = new ImageView(context); 
    imageView.setImageResource(imageResId); 
    imageView.setLayoutParams(imageParams); 

    // modify root layout 
    linearLayout.setOrientation(LinearLayout.HORIZONTAL); 
    linearLayout.addView(imageView, 0); 

    return toast; 
}

這隻有在吐司的佈局是'LinearLayout'類型時纔有效。沒有聯繫afaik Toast將始終有一個LinearLayout。您的代碼通過不添加圖像來處理此問題，但值得注意的是，此解決方案不是獨立於設備/版本的。 – Graeme

@Graeme你是對的。謝謝你的提示。更好的方法是在自己的LinearLayout中重新創建Toast。當我找到時間時，我會更新我的答案。 – Knickedi

簡單地說，使用以下：

Toast toast = new Toast(myContext); 
ImageView view = new ImageView(myContext); 
view.setImageResource(R.drawable.image_icon); 
toast.setView(view); 
toast.show();

Knickedi的解決方案是好的，但如果你只需要在文本旁邊的圖標，你可以利用的事實吐司有一個預先定義的TextView與相同的ID並在TextV上設置圖標IEW：

Toast toast = Toast.makeText(context, text, Toast.LENGTH_SHORT); 
TextView tv = (TextView) toast.getView().findViewById(android.R.id.message); 
if (null!=tv) { 
    tv.setCompoundDrawablesWithIntrinsicBounds(icon, 0, 0, 0); 
    tv.setCompoundDrawablePadding(context.getResources().getDimensionPixelSize(R.dimen.padding_toast));

我覺得這是更好的，我們表明，我們傳遞給makeImageToast功能在圖像上吐司的文字... 所以我遮擋Knickedi碼和：

public class utility { 

public static Toast makeImageToast(Context context, int imageResId, CharSequence text, int length) { 
    Toast toast = Toast.makeText(context, text, length); 

    View rootView = toast.getView(); 
    LinearLayout linearLayout = null; 
    View messageTextView = null; 

    // check (expected) toast layout 
    if (rootView instanceof LinearLayout) { 
     linearLayout = (LinearLayout) rootView; 

     if (linearLayout.getChildCount() == 1) { 
      View child = linearLayout.getChildAt(0); 

      if (child instanceof TextView) { 
       messageTextView = (TextView) child; 
       ((TextView) child).setGravity(Gravity.CENTER); 

      } 
     } 
    } 

    // cancel modification because toast layout is not what we expected 
    if (linearLayout == null || messageTextView == null) { 
     return toast; 
    } 

    ViewGroup.LayoutParams textParams = messageTextView.getLayoutParams(); 
    ((LinearLayout.LayoutParams) textParams).gravity = Gravity.CENTER; 

    // convert dip dimension 
    float density = context.getResources().getDisplayMetrics().density; 
    int imageSize = (int) (density * 25 + 0.5f); 
    int imageMargin = (int) (density * 15 + 0.5f); 

    // setup image view layout parameters 
    LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(imageSize, imageSize); 
    imageParams.setMargins(0, 0, imageMargin, 0); 
    imageParams.gravity = Gravity.CENTER; 

    // setup image view 
    ImageView imageView = new ImageView(context); 
    imageView.setImageResource(imageResId); 
    imageView.setLayoutParams(imageParams); 


    // modify root layout 
    linearLayout.setOrientation(LinearLayout.HORIZONTAL); 
    linearLayout.setBackgroundResource(imageResId); 
    linearLayout.setGravity(Gravity.CENTER); 
    linearLayout.setHorizontalGravity(Gravity.CENTER); 
    linearLayout.setHorizontalGravity(Gravity.CENTER); 
    //addView(imageView, 0); 

    return toast; 
}

}

，這是使用它：

utility.makeImageToast(getApplicationContext(), 
       R.drawable.your_image,"your_text",Toast.LENGTH_LONG).show();
