Toast Message Prompt

Four types, normal, change position, with diagram, custom

First, the layout is built with four buttons corresponding to each other.

<?XML version= "1.0" encoding= "Utf-8"?><Relativelayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent" >    <LinearLayoutAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:layout_centerinparent= "true"android:orientation= "vertical"        >        <ButtonAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:id= "@+id/toast_btn1"Android:text= "Show Toast"            />                <ButtonAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:id= "@+id/toast_btn2"Android:text= "Change position toast"            />                <ButtonAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:id= "@+id/toast_btn3"Android:text= "With graph toast"            />                <ButtonAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:id= "@+id/toast_btn4"Android:text= "Full Custom toast"            />    </LinearLayout></Relativelayout>

Then create a new layout to put the custom

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical" >    <TextViewAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:gravity= "Center"Android:text= "Static Flow"        />    <ImageViewAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:src= "@drawable/four"        />    <TextViewAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:gravity= "Center"Android:text= "self-defined static flow" is mine.        /></LinearLayout>

Then write the master file

 PackageCom.example.deemo;Importandroid.app.Activity;ImportAndroid.os.Bundle;Importandroid.view.Gravity;ImportAndroid.view.LayoutInflater;ImportAndroid.view.View;ImportAndroid.view.View.OnClickListener;ImportAndroid.widget.ImageView;Importandroid.widget.LinearLayout;ImportAndroid.widget.Toast; Public classMainactivityextendsActivity {PrivateView toast_layout; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.main);    Initevent (); }        Private voidInitevent () {//Initialize a click event (response event)Findviewbyid (R.ID.TOAST_BTN1). Setonclicklistener (NewOnclicklistener () {@Override Public voidOnClick (View v) {showToast1 ();        }        }); Findviewbyid (R.ID.TOAST_BTN2). Setonclicklistener (NewOnclicklistener () {@Override Public voidOnClick (View arg0) {showToast2 ();        }        }); Findviewbyid (R.ID.TOAST_BTN3). Setonclicklistener (NewOnclicklistener () {@Override Public voidOnClick (View arg0) {showToast3 (); }}); Findviewbyid (R.ID.TOAST_BTN4). Setonclicklistener (NewOnclicklistener () {@Override Public voidOnClick (View arg0) {showToast4 ();    }        }); }    Private voidShowToast1 () {//Show Default ToastToast toast = Toast.maketext ( This, "Static flow is my wife", Toast.length_long);//the last one is time .toast.show (); //Toast.maketext (This, "default", Toast.length_long). Show ();//write a different way to play ...     }    Private voidShowToast2 () {//Show custom Locations ToastToast toast = Toast.maketext ( This, "Change the position, or my wife.", Toast.length_long); Toast.setgravity (Gravity.top,0, 100);    Toast.show (); }    Private voidShowToast3 () {//with a pictureToast toast = Toast.maketext ( This, "Look at my wife!", Toast.length_long); LinearLayout Toast_layut=(LinearLayout) Toast.getview (); ImageView IV=NewImageView ( This);        Iv.setimageresource (R.drawable.four); Toast_layut.addview (iv,1);//The second parameter is the location where you can change thetoast.show (); }    Private voidShowToast4 () {//fully customizableLayoutinflater Inflater = Layoutinflater.from ( This); View Toast_view= Inflater.inflate (R.layout.toast_layout,NULL); Toast Toast=NewToast ( This);        Toast.setview (Toast_view);    Toast.show (); }}

Here the button with the response to the event, actually carry out the initialization and then use the internal class also can it.
