How to implement dialog like truecaller

I am trying to implement the app similar to true caller,I am able to get the phone number when the phone rings using broadcast receiver and opening the MyCustomDialog Activity
This is my receiver class by which I am getting the Call State that the call is starts or ends. In this, I make some methods which I am using in CallReceiver.java
PhonecallReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import java.util.Date;
public abstract class PhonecallReceiver extends BroadcastReceiver
{
private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;
private static boolean isIncoming;
private static String savedNumber;
#Override
public void onReceive(Context context, Intent intent)
{
try
{
if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL"))
{
savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
}
else
{
String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
int state = 0;
if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
state = TelephonyManager.CALL_STATE_IDLE;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
state = TelephonyManager.CALL_STATE_OFFHOOK;
}
else if(stateStr.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
state = TelephonyManager.CALL_STATE_RINGING;
}
onCallStateChanged(context, state, number);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
//Derived classes should override these to respond to specific events of interest
protected void onIncomingCallStarted(Context ctx, String number, Date start){}
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end){}
public void onCallStateChanged(Context context, int state, String number)
{
if(lastState == state)
{
//No change, debounce extras
return;
}
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
isIncoming = true;
callStartTime = new Date();
savedNumber = number;
onIncomingCallStarted(context, number, callStartTime);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if (isIncoming)
{
onIncomingCallEnded(context,savedNumber,callStartTime,new Date());
}
case TelephonyManager.CALL_STATE_IDLE:
if(isIncoming)
{
onIncomingCallEnded(context, savedNumber, callStartTime, new Date());
}
}
lastState = state;
}
}

By implementing all this stuff I am getting the desired output
Please guide me how to make this activity dialog dragable like the popup of the truecaller app.
I am searching for the dialog similar to this image ,

It is possible through OnTouchListener, Try this https://github.com/andreilisun/Swipe-To-Dismiss-Dialog
The Dialog is draggable, I have changed the SwipeDimissDialog to remove dismissal of Dialog in the following class -
public class SwipeDismissDialog extends FrameLayout {
private final Params params;
private View dialog;
protected SwipeDismissDialog(#NonNull Context context, Params params) {
super(context);
this.params = params;
init();
}
private void init() {
setOnClickListener(overlayClickListener);
setBackgroundColor(params.overlayColor);
dialog = params.view;
if (dialog == null) {

if (layoutParams == null) {
layoutParams = new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
} else {
layoutParams.gravity = Gravity.CENTER;
}
dialog.setOnTouchListener(touchListener);
addView(dialog, layoutParams);
}
#Override

return true;

return false;
}

layoutParams.format = PixelFormat.TRANSLUCENT;
windowManager.addView(this, layoutParams);
return this;
}
public void cancel() {
if (params.cancelListener != null) {
params.cancelListener.onCancel(dialog);
}
if (params.dismissOnCancel) {
dismiss();
}
}
public void dismiss() {
dialog.setOnTouchListener(null);
removeView(dialog);
WindowManager windowManager = (WindowManager)
getContext().getSystemService(Context.WINDOW_SERVICE);
windowManager.removeViewImmediate(this);
}
private void dismiss(SwipeDismissDirection direction) {
if (params.swipeDismissListener != null) {
params.swipeDismissListener.onSwipeDismiss(this, direction);
}
dismiss();
}

view.setX(view.getX() + eventDx);
view.setY(view.getY() + eventDy);
//view.invalidate();
lastEventX = eventX;
lastEventY = eventY;
break;
}
}
return true;
}
};
private final OnClickListener overlayClickListener = new OnClickListener() {
#Override
public void onClick(View v) {
cancel();
}
};
public static class Builder {
private final Params params;
private final Context context;

Cannot use this in Builder Android Service

I am trying to use a Bulider from a library that i have imported in my project but for some reason the Builder doesn't accept 'this' as Service context. if anyone can help me out i would truly appreciate it. Thanks

The View.OnSystemUiVisibilityChangeListener is not work in android Service

I was wondering whether to display SystemUI and Listenering. The window is created in Service

When I start service,Other App changed to FULLSCREEN or not ,I can't get the log "systemUI onSystemUiVisibilityChange ="
Can someone explain the behaviour? Why can't listener the change?

You can try to add the listener before calling addView.

Android Drag and Drop functionality

Is there some way to implement drag and drop functionality in API 8 Android?
Looked here, but it appears after API 11.
I need to drag view from one LinearLayout to another. Ho can i implement this on API 8?

Try like this
import android.app.Activity;
import android.content.ClipData;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Point;
import android.graphics.Rect;
import android.os.Bundle;
import android.view.DragEvent;
import android.view.View;
import android.view.View.DragShadowBuilder;
import android.view.View.OnDragListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity extends Activity {
ListView source = null;
TextView target1 = null;
TextView target2 = null;
TextView target3 = null;
String[] listItems = {"Samsung", "Apple", "Google", "Nokia"};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
source = (ListView)findViewById(R.id.dragSource);
target1 = (TextView) findViewById(R.id.dragTarget1);
target2 = (TextView) findViewById(R.id.dragTarget2);
target3 = (TextView) findViewById(R.id.dragTarget3);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
source.setAdapter(adapter);
// Start Drag
source.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = listItems[position];
ClipData data = ClipData.newPlainText("DragIt", item);
source.startDrag(data, new MyShadowBuilder(view), null, 0);
}
});
// Handle Drag
target1.setOnDragListener(new MyDragListener());
target2.setOnDragListener(new MyDragListener());
target3.setOnDragListener(new MyDragListener());
}
// Drag Shadow
private class MyShadowBuilder extends DragShadowBuilder {
public MyShadowBuilder(View v) {
super(v);
}
#Override
public void onDrawShadow(Canvas canvas) {
// Set Drag image background or anything you want
int width = getView().getWidth();
int height = getView().getHeight();
Paint paint = new Paint();
paint.setColor(0x55858585);
canvas.drawRect(new Rect(0, 0, width, height), paint);
super.onDrawShadow(canvas);
}
#Override
public void onProvideShadowMetrics(Point shadowSize,
Point shadowTouchPoint) {
int width = getView().getWidth();
int height = getView().getHeight();
shadowSize.set(width, height);
shadowTouchPoint.set(width/2, height);
}
}
// Drag Listener
private class MyDragListener implements OnDragListener {
private final int DEFAULT_BG_COLOR = 0xFF858585;
private final int HIGHLIGHT_BG_COLOR = 0xFF0000FF;
#Override
public boolean onDrag(View v, DragEvent event) {
if(event.getAction() == DragEvent.ACTION_DRAG_ENTERED) {
v.setBackgroundColor(HIGHLIGHT_BG_COLOR);
}
else if(event.getAction() == DragEvent.ACTION_DRAG_EXITED) {
v.setBackgroundColor(DEFAULT_BG_COLOR);
}
else if(event.getAction() == DragEvent.ACTION_DROP) {
// Perform drop
ClipData clip = event.getClipData();
ClipData.Item item = clip.getItemAt(0);
String text = item.getText().toString();
((TextView) v).setText(text);
v.setBackgroundColor(DEFAULT_BG_COLOR);
}
// Send true to listen All Drag Events.
return true;
}
}
}
XML is like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="161dp"
android:layout_height="fill_parent"
android:background="#FF858585"
android:orientation="vertical" >
<TextView
android:id="#+id/dragTarget1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.04"
android:text="Drop Here"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/dragTarget2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.04"
android:text="Drop Here"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/dragTarget3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.04"
android:text="Drop Here"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/dragSource"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>

ImageView isn't visible and motion event isn't works well

i'm writing service class that has image overlay
imageView overlay was visible, but it isn't visible after i added imageview resize code.
Also, MotionEvent for resized imageview isn't works well
Why imageview overlay isn't visible and MotionEvent isn't works well?
Could you help me to solve this problem?
here's my code

The code that you are complaining about isn't adding the ImageView - mTouchDetector - to your layout. You must add it in order for it to be visible if you are using plain Java instead of XML. Look at your first example (the working one):
mWindowManager.addView(mTouchDetector, mParams);
That's the idea here.
