Custom Dialog width occupies full screen and dialog width

Custom Dialog width occupies full screen and dialog width
1. Custom Dialog inherits the Dialog

public class MyDialog extends Dialog {

 

2. Set a style for Dialog

Create new style inheritance in style

@ Android: style/Theme. Dialog or @ android: style/Theme. Holo. Dialog

• Set style to remove border
• Remove title
• Set window transparency
• The Setting Dialog Box can disappear.
• Set Animation

 

<! -- <Style name = "MyDialog" parent = "@ android: style/Theme. dialog "> --> <style name =" MyDialog "parent =" @ android: style/Theme. holo. dialog "> <! -- Whether a Border exists --> <item name = "android: windowFrame"> @ null </item> <! -- Whether it is above the suspended Activity --> <item name = "android: Refreshing wisfloating"> true </item> <! -- Title --> <item name = "android: windowNoTitle"> true </item> <! -- Shadow --> <item name = "android: javaswistranslucent"> true </item> <! -- Translucent --> <! -- Enter and exit the animation --> <item name = "android: windowAnimationStyle"> @ style/MyDialogAnimation </item> <! -- Disappears from the outside --> <item name = "android: windowCloseOnTouchOutside"> true </item> </style> <style name = "MyDialogAnimation"> <! -- Enter --> <item name = "android: windowEnterAnimation"> @ anim/dialog_enter </item> <! -- Exit --> <item name = "android: javaswexitanimation"> @ anim/dialog_exit </item> </style>

 

Enter Animation

dialog_enter

dialog_exit

The built-in system can be found and used directly in the SDK.

<set xmlns:android="http://schemas.android.com/apk/res/android"        android:shareInterpolator="false" >    <scale android:fromXScale="0.9" android:toXScale="1.0"           android:fromYScale="0.9" android:toYScale="1.0"           android:pivotX="50%" android:pivotY="50%"                   android:duration="200" />    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"            android:duration="200" />   </set>

Exit

<set xmlns:android="http://schemas.android.com/apk/res/android"     android:shareInterpolator="false">    <scale        android:duration="200"        android:fromXScale="1.0"        android:fromYScale="1.0"        android:pivotX="50%"        android:pivotY="50%"        android:toXScale="0.9"        android:toYScale="0.9"/>    <alpha        android:duration="200"        android:fromAlpha="1.0"        android:toAlpha="0.0"/></set>

3. Set the style in the constructor

Context mContext;    public MyDialog(Context context) {        super(context, R.style.MyDialog);        this.mContext=context;            }

Iv. Set Layout

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.layout_dialog);    }

The layout file contains two textviews.

5. Rewrite the show method and set the width and height.

@ Override public void show () {super. show ();/*** set the width to full screen. You must set the width to the back of show */LayoutParams layoutParams = getWindow (). getAttributes (); layoutParams. gravity = Gravity. BOTTOM; layoutParams. width = LayoutParams. MATCH_PARENT; layoutParams. height = LayoutParams. WRAP_CONTENT; getWindow (). getDecorView (). setPadding (0, 0, 0, 0); getWindow (). setAttributes (layoutParams );}

 

Vi. Complete Dialog class

/*** Dialog July 30, 2016 */public class MyDialog extends Dialog {Context mContext; public MyDialog (Context context) {super (context, R. style. myDialog); this. mContext = context;} @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. layout_dialog) ;}@ Override public void show () {super. show ();/*** set the width to full screen. You must set the width to the back of show */LayoutParams layoutParams = getWindow (). getAttributes (); layoutParams. gravity = Gravity. BOTTOM; layoutParams. width = LayoutParams. MATCH_PARENT; layoutParams. height = LayoutParams. WRAP_CONTENT; getWindow (). getDecorView (). setPadding (0, 0, 0, 0); getWindow (). setAttributes (layoutParams );}}
