Android Toast就像弹出

Question

我一直在使用Toast，但android是否有类似的功能，但是消息会一直显示直到用户将其关闭为止。

Answer 1

as per my knowledge you have three options to do this task.

1. Custome Toast
2. PopupWindow

3. SnackBar

   CostumeToast

     void errortoast(String Msg) { LayoutInflater inflater = getLayoutInflater(); View layout = inflater.inflate(R.layout.toast, (ViewGroup) findViewById(R.id.custom_toast_layout)); TextView text = (TextView) layout.findViewById(R.id.textToShow); text.setText(Msg); Toast toast = new Toast(getApplicationContext()); toast.setGravity(Gravity.TOP | 0, 0, 0); toast.setDuration(Toast.LENGTH_SHORT); toast.setView(layout); toast.show(); } 

toast.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/custom_toast_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="@android:color/background_dark"
android:orientation="horizontal"
android:padding="8dp" >

<TextView
    android:id="@+id/textToShow"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableLeft="@android:drawable/ic_dialog_alert"
    android:text="Error"
    android:textColor="#FFFFFF" 
    android:textSize="19sp"/>

</LinearLayout>

PopUpWindow

    public void displaypopup() {

    LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
            .getSystemService(LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.popup, null);
    final PopupWindow popupWindow = new PopupWindow(popupView,
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    Button btnDismiss = (Button) popupView.findViewById(R.id.dismiss);
    btnDismiss.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            popupWindow.dismiss();
        }
    });
    popupWindow.showAtLocation(popupView, Gravity.TOP, 0, 0);
}

popup.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/lytpopup"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView
    android:id="@+id/tvmessagedialogtitle"
    android:layout_width="wrap_content"

    android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceLarge" 
    android:layout_gravity="center_horizontal"
    android:text="Hello" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"
    android:layout_gravity="center_horizontal"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/bmessageDialogYes"
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:background="#cb4c4c"
        android:minHeight="0dp"
        android:minWidth="0dp"
        android:paddingBottom="5dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="5dp"
        android:text="View"
        android:textColor="#FFFFFF"
        android:textSize="18dip" />

    <Button
        android:id="@+id/dismiss"
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#77aa5c"

        android:minWidth="0dp"
        android:paddingBottom="5dp"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:paddingTop="5dp"
        android:text="Dismiss"
        android:textColor="#FFFFFF"
        android:textSize="18dip"
        android:textStyle="normal"
        android:typeface="normal" />
</LinearLayout>

Answer 2

You can use Dialog.
Read this page. http://developer.android.com/reference/android/app/Dialog.html

Answer 3

You can try Android Crouton :

Android Croutons

Github Link

Crouton is a class that can be used by Android developers that feel the need for an alternative to the Context insensitive Toast.

A Crouton will be displayed at the position the developer decides. Standard will be the top of an application window. You can line up multiple Croutons for display, that will be shown one after another.
