Android custom Dialog tool class, androiddialog

Because of project requirements, the system pop-up box can no longer meet our needs, we need a variety of pop-up boxes, then we need to customize the pop-up box.

Create the layout file dialog_layout.xml and copy the following content.

<? Xml version = "1.0" encoding = "UTF-8"?>
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: orientation = "vertical">

<LinearLayout
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: layout_marginLeft = "5dp"
Android: layout_marginRight = "5dp"
Android: layout_marginTop = "5dp"
Android: background = "@ drawable/shape_linearlayout"
Android: orientation = "vertical"
>

<LinearLayout
Android: layout_width = "match_parent"
Android: layout_height = "150dp"
Android: gravity = "center_vertical"
Android: orientation = "vertical">

<TextView
Android: id = "@ + id/txt_dialog_message"
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: gravity = "center"
Android: layout_marginLeft = "20dp"
Android: layout_marginRight = "20dp"
Android: text = "TextView"/>
</LinearLayout>

<View
Android: layout_width = "match_parent"
Android: layout_height = "1dp"
Android: background = "@ color/line"/>

<LinearLayout
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: layout_marginLeft = "5dp"
Android: layout_marginRight = "5dp"
Android: layout_marginBottom = "1dp">

<Button
Android: id = "@ + id/btn_dialog_go"
Android: layout_width = "0dp"
Android: layout_height = "40dp"
Android: layout_weight = "1"
Android: background = "@ drawable/linearlayout"
Android: text = "OK"
Android: textColor = "@ color/blue"/>

<View
Android: id = "@ + id/dialog_bg"
Android: layout_width = "1dp"
Android: layout_height = "40dp"
Android: background = "@ color/line"/>

<Button
Android: id = "@ + id/btn_dialog_add"
Android: layout_width = "0dp"
Android: layout_height = "40dp"
Android: layout_weight = "1"
Android: background = "@ drawable/linearlayout"
Android: text = "cancel"
Android: textColor = "@ color/blue"/>
</LinearLayout>
</LinearLayout>

</LinearLayout>

 

Create a java class DialogUtil. java

Public class DialogUtil {

Private static DialogUtil dialogUtil;
Private Dialog dialog;
Private TextView message;
Private Button firstBtn;
Private Button secondBtn;
Private onButtnClickListener buttnClickListener;

Public static DialogUtil getDialogInstance (Context context ){
If (null = dialogUtil ){
DialogUtil = new DialogUtil (context );
}
Return dialogUtil;
}

Private DialogUtil (Context context ){
InitDialog (context );
}

Public void setMessage (String message ){
If (null! = Message &&! Message. equals ("")){
This. message. setText (message );
}

}

Private void initDialog (Context context ){
Dialog = new Dialog (context );

Dialog. setContentView (R. layout. dialog_layout );
Dialog. setCanceledOnTouchOutside (false );
Window window = dialog. getWindow ();
Dialog. setCanceledOnTouchOutside (true );
WindowManager. LayoutParams params = window. getAttributes ();
Params. width = ScreenUtils. getScreenWidth (context)
-ScreenUtils. getScreenWidth (context)/4;
Params. height = LayoutParams. WRAP_CONTENT;
Params. gravity = Gravity. CENTER;
Window. setAttributes (params );
Window. setWindowAnimations (R. style. displayStyle );
Message = (TextView) dialog.findViewById(R.id.txt _ dialog_message );
FirstBtn = (Button) dialog. findViewById (R. id. btn_dialog_go );
SecondBtn = (Button) dialog. findViewById (R. id. btn_dialog_add );
FirstBtn. setOnClickListener (new OnClickListener (){

@ Override
Public void onClick (View v ){
// TODO Auto-generated method stub
If (null! = ButtnClickListener)
ButtnClickListener. onFirstBtnClick (v );
}
});
SecondBtn. setOnClickListener (new OnClickListener (){

@ Override
Public void onClick (View v ){
// TODO Auto-generated method stub
If (null! = ButtnClickListener)
ButtnClickListener. onSecondBtnClick (v );
}
});
}

Public void showDialog (){
If (dialog! = Null &&! Dialog. isShowing ()){
Dialog. show ();
}
}

Public void dissmissDialog (){
If (dialog! = Null & dialog. isShowing ()){
Dialog. dismiss ();

}
}

Public void setOnButtnClickListener (onButtnClickListener buttnClickListener ){
This. buttnClickListener = buttnClickListener;
}

Public interface onButtnClickListener {
Public void onFirstBtnClick (View v );

Public void onSecondBtnClick (View v );
}

}

The dialog tool class adopts the single-column mode, and the calling process is

1. Get the object first

DialogUtil. getDialogInstance (context );

2. Set text information

SetMessage (String message );

3. Set the single-host event of the button

SetOnButtnClickListener (onButtnClickListener buttnClickListener );

4. Display dialog

ShowDialog ();

Now the custom pop-up box is complete.
