是否有可能以编程方式将图像添加到举杯弹出?
Answer 1:
是的 ,你可以使用的setView()方法,使用这种方法,你可以自定义吐司按照您的要求添加的ImageView或任何视图到Toast通知。
在这里,我已经创建被充气到吐司通知自定义布局文件,然后我已经使用的setView()方法用于这种布局中吐司通知。
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();
Answer 2:
简单地说,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();
Answer 3:
您可以通过编程创建任何视图(因为我假设你是问如何做到这一点不使用LayoutInflater)和呼叫的setView上所做的吐司。
//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();
Answer 4:
Knickedi的解决方案是好的,但如果你只需要在文本旁边的图标,你可以利用的事实吐司有相同ID的预先定义的TextView,并设置TextView的图标:
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));
Answer 5:
总有创建一个自定义布局的可能性。 有一个事实,我不喜欢有关:它打破了系统默认UI敬酒。 这可以在不同的平台和实现不同。 有使用系统默认的资源,所以我决定砍烤面包和强制图像到它没有简单的方法。
提示 :你可以得到这样默认的资源:
Toast.makeToast(context, "", 0).getView().getBackground()
下面是将在烤面包消息的前方显示图像的助手: Helper.makeImageToast(context, R.drawable.my_image, "Toast with image", Toast.LENGTH_SHORT).show()
我用它来表示成功,信息或错误。 使举杯信息更好,更具表现力...
(值得一提的是,这样的事实,内部敬酒使用黑客基地LinearLayout
所以不是制度和实施独立的。见注释)。
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;
}
Answer 6:
我觉得这是更好的,我们表明,我们传递给makeImageToast功能在图像上敬酒的文字...所以我遮挡Knickedi码和:
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;
}
}
这就是使用它:
utility.makeImageToast(getApplicationContext(),
R.drawable.your_image,"your_text",Toast.LENGTH_LONG).show();
Answer 7:
Toast aa = Toast.makeText(getBaseContext(), "OPEN",Toast.LENGTH_SHORT);
ImageView cc = new ImageView(getBaseContext());
cc.setImageResource(R.drawable.a);
aa.setView(cc);
aa.show();
