Animated customized dialog or popup transparent layout with Button and Linear layout gradient effect in android

The image shown below is an example of animated customized popup with transparent layout for button and linearlayout, and the linearlayout and button is given gradient effect


How to get a transparent layout? For that we need to use a transparent class


TransparentPanel.java
package com.popup.design.layers;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import android.graphics.Paint.Style;
import android.util.AttributeSet;
import android.widget.LinearLayout;

public class TransparentPanel extends LinearLayout
{
private Paint innerPaint, borderPaint ;

public TransparentPanel(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}

public TransparentPanel(Context context) {
super(context);
init();
}

private void init() {
innerPaint = new Paint();
innerPaint.setARGB(225, 0, 0, 0);
innerPaint.setAntiAlias(true);

borderPaint = new Paint();
borderPaint.setARGB(255, 0, 0, 0);
borderPaint.setAntiAlias(true);
borderPaint.setStyle(Style.STROKE);
borderPaint.setStrokeWidth(2);
}

public void setInnerPaint(Paint innerPaint) {
this.innerPaint = innerPaint;
}

public void setBorderPaint(Paint borderPaint) {
this.borderPaint = borderPaint;
}

@Override
protected void dispatchDraw(Canvas canvas) {

RectF drawRect = new RectF();
drawRect.set(0,0, getMeasuredWidth(), getMeasuredHeight());

canvas.drawRoundRect(drawRect, 5, 5, innerPaint);
canvas.drawRoundRect(drawRect, 5, 5, borderPaint);

super.dispatchDraw(canvas);
}
}


We need to use this transparentPanel class in the xml file, where we need the transparent layout, in the popup.xml we are using the com.popup.design.layers.TransparentPanel instead of LinearLayout, see in the code


popup.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@drawable/white"
android:layout_width="fill_parent" android:layout_height="fill_parent">

<Button android:id="@+id/show_popup_button" android:layout_gravity="bottom"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_marginBottom="25px" android:text="Show Popup" />

<com.popup.design.layers.TransparentPanel
android:id="@+id/popup_window" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:orientation="vertical"
android:layout_gravity="bottom" android:gravity="left" android:padding="1px"
android:background="@drawable/white">

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:gravity="right"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:background="@drawable/button_bar_gradient">

<Button android:id="@+id/hide_popup_button"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_marginTop="5px"
android:layout_marginRight="10px" android:paddingLeft="5px"
android:paddingRight="5px" style="?android:attr/buttonStyleSmall"
android:textStyle="bold" android:textColor="@drawable/white"
android:textSize="12px" android:text=" Close " android:background="@drawable/button_close"/>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="1px" android:layout_marginTop="5px"
android:layout_below="@+id/hide_popup_button" android:background="@drawable/white" />
</RelativeLayout>

<TextView android:id="@+id/location_name"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:textStyle="bold" android:textSize="16px" android:textColor="@drawable/white"
android:layout_marginTop="5px" android:layout_marginLeft="5px" />

<TextView android:id="@+id/location_description"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:textColor="@drawable/white" android:layout_margin="5px" />

</com.popup.design.layers.TransparentPanel>

</FrameLayout>


Customized Popup is the com.popup.design.layers.TransparentPanel, initially we will hide this layout, and on the button click will show this layout. The java code is as follows


AnimatePopup.java
package com.popup.design;

import com.popup.design.layers.TransparentPanel;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.TextView;

/**
*
* @author http://www.android-codes-examples.blogspot.com/
*
*/
public class AnimatePopup extends Activity {

private Animation animShow, animHide;

@Override
public void onCreate(Bundle icicle) {

super.onCreate(icicle);

setContentView(R.layout.popup);

initPopup();
}

private void initPopup() {

final TransparentPanel popup = (TransparentPanel) findViewById(R.id.popup_window);

// Start out with the popup initially hidden.
popup.setVisibility(View.GONE);


animShow = AnimationUtils.loadAnimation( this, R.anim.popup_show);
animHide = AnimationUtils.loadAnimation( this, R.anim.popup_hide);

final Button showButton = (Button) findViewById(R.id.show_popup_button);
final Button hideButton = (Button) findViewById(R.id.hide_popup_button);
showButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
popup.setVisibility(View.VISIBLE);
popup.startAnimation( animShow );
showButton.setEnabled(false);
hideButton.setEnabled(true);
}});

hideButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
popup.startAnimation( animHide );
showButton.setEnabled(true);
hideButton.setEnabled(false);
popup.setVisibility(View.GONE);
}});


final TextView locationName = (TextView) findViewById(R.id.location_name);
final TextView locationDescription = (TextView) findViewById(R.id.location_description);

locationName.setText("Animated Popup");
locationDescription.setText("Animated popup is created by http://www.android-codes-examples.blogspot.com/"
+ " Transparent layout is used on this example, and animation xml is also used"
+ " on this example. Have a Good day guys.");
}
}


For giving gradient effect we need to use this xml file as the background for the linearlayout or button. The xml file is


button_bar_gradient.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient android:startColor="#C0C0C0"
android:endColor="#505050"
android:angle="90"/>
<corners android:radius="2px" />
</shape>



In the popup.xml we had used the button_bar_gradient as a background. This button_bar_gradient.xml will be in drawable folder.
