I am unable to find the way to create a popup like info window in map . I have to use it to show the three button inside
Yes
later
No
these three options are clickable.
The pop up will show above three button in vertical manner in recycler view . I have created recycler view and pop up view but how to show it like a Tooltip with clickabe
you can use PopupWindow, its starting with API +23

I have a fragment defined in my project plus an activity with a button. What I want is to launch the fragment with that button onclick listener, enter a value in the edit text defined in the fragment's xml layout file and press another button2 present in the fragment. Now what I want is that the button2 return's the text value and open's the activity again. I can then handle what happens to that value.

It sound like what you need is a Dialog. Have a look at the development site: http://developer.android.com/guide/topics/ui/dialogs.html
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.dialog_fire_missiles)
.setPositiveButton(R.string.fire, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// FIRE ZE MISSILES!
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
return builder.create();
I want to "Drag and Drop" items from a PopupWindow into the underlying View. The problem now is, when i dismiss the PopupWindow after a long click on an item, the underlying view does not receive any MotionEvents. This problem basically breaks down to delegating MotionEvents between views like in the drag-and-drop-between-views-issue as discussed here. A solution was proposed here but in my case this is not an option. I can't use an overlay view that lies on top of the PopupWindow, can I?
The code below is a simplified version of my problem. I basically have one button that brings up the PopupWindow. On a long click on that PopupWindow it gets dismissed. Now the MotionEvents should be send to the underlying view again, but that does not happen (as you can see in the log output).

import android.os.Bundle;

findViewById(R.id.contents).setOnTouchListener(this);
}
#Override
public void onClick(View v) {
final PopupWindow p = new PopupWindow(this);
p.setContentView(new Button(this));
p.setHeight(100);
p.setWidth(100);
p.showAtLocation(findViewById(R.id.contents), Gravity.CENTER, 0, 0);
p.getContentView().setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
v.post(new Runnable() {
#Override
public void run() {
p.dismiss();
}
});
return false;
}
});
}

Log.d("", "Action: " + event);
return true;

Here is the simple XML layout I use:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="#+id/contents" >
<Button
android:id="#+id/b1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
I'm very new to Android development and just started to study.
What I'm trying is to add a button and when that button is pressed a text "my first project" to get displayed in the text view.
With the help of some experts I created the button and text view.
So the button is showing in the simulator but when I click that button nothing happens.
Can anyone please help me with how can I display the text when pressing the button?
.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/txtView"
android:layout_width="150dp"
android:layout_height="150dp"
android:text="#string/hello" />
<Button
android:id="#+id/mybtn"
android:layout_width="50dp"
android:layout_height="30dp" />
<TextView
android:id="#+id/viewwidth"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/viewheight"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
.java
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.TextView;
import android.view.View;
import android.widget.Toast;
public class NameonbuttonclickActivity extends Activity implements View.OnClickListener {
Button mybtn;
TextView txtView;
String hello;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.main);
super.onCreate(savedInstanceState);
mybtn= new Button(this);
txtView=new TextView(this);
mybtn.setOnClickListener(this);
printmyname();
mybtn = (Button)findViewById(R.id.mybtn);
txtView=(TextView)findViewById(R.id.txtView);
txtView = (TextView)findViewById(R.id.viewwidth);
txtView = (TextView)findViewById(R.id.viewheight);
hello="This is my first project";
//setContentView(mybtn);
// setContentView(R.layout.main);
}
public void onClick(View view){
txtView.setText(hello);
//printmyname();
Toast.makeText(NameonbuttonclickActivity.this, hello, Toast.LENGTH_LONG).show();
}
private void printmyname(){
System.out.println("coming");
}
}
You can do like this:
String hello;
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.main);
super.onCreate(savedInstanceState);
mybtn = (Button)findViewById(R.id.mybtn);
txtView=(TextView)findViewById(R.id.txtView);
txtwidth = (TextView)findViewById(R.id.viewwidth);
hello="This is my first project";
mybtn.setOnClickListener(this);
}
public void onClick(View view){
txtView.setText(hello);
}
Check your textview names. Both are same . You must use different object names and you have mentioned that textview object which is not available in your xml layout file.
Hope this will help you.
First create xml file as follows. Create one textview and a button:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<Button
android:id="#+id/mybutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click Me" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
The first TextView is created by default. You can leave or remove it if you want.
Next one is to create a button
The next one is TextView where you want to display text.
Now coming to the main activity code...
package com.android.example.simple;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class SimpleActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final TextView textView=(TextView)findViewById(R.id.textView1);
final Button button1 = (Button)findViewById(R.id.mybutton);
//Implement listener for your button so that when you click the
//button, android will listen to it.
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
textView.setText("You clicked the button");
} });
}
}
This is because you DON'T associated the OnClickListener() on the button retrieve from the XML layout.
You don't need to create object because they are already created by the Android system when you inflate XML file (with the Activity.setContentLayout( int resourceLayoutId ) method).
Just retrieve them with the findViewById(...) method.
Just check your code in .java class
You had written below line
mybtn.setOnClickListener(this);
before initializing the mybtn object I mean
mybtn = (Button)findViewById(R.id.mybtn);
just switch this two line or put that line "mybtn.setOnClickListener(this)" after initializing your mybtn object and you will get the answer what you want..
Try this
public void onClick(View view){
txtView.setText("hello");
//printmyname();
Toast.makeText(NameonbuttonclickActivity.this, "hello", Toast.LENGTH_LONG).show();
}
Also in toast use "Hello"
you use this as txtView.setText("hello");
MainActivity.java:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {
Button button1;
TextView textView1;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1=(Button)findViewById(R.id.button1);
textView1=(TextView)findViewById(R.id.textView1);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
textView1.setText("TextView displayed Successfully");
}
});
}
}
activity_main.xml:
<?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" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click here" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
public void onCreate(Bundle savedInstanceState)
{
setContentView(R.layout.main);
super.onCreate(savedInstanceState);
mybtn = (Button)findViewById(R.id.mybtn);
txtView=(TextView)findViewById(R.id.txtView);
mybtn .setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
txtView.SetText("Your Message");
}
});
}
Check this:
hello.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View paramView) {
text.setText("hello");
}
});
I am looking for a way to close a custom dialog with a button that is inside the xml used in the dialog, alternatively closing it by pressing anywhere on the dialog. What I have is this; a layout with a Image Button that brings up the custom dialog with the content. I have setCanceledOnTouchOutside(true); and that works, but I need the dialog to fill up most of the screen and it can be hard for the user to click in the small space that is available. So how do I do this?
My java code:
import android.app.Activity;
import android.app.Dialog;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
public class Rose extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.setRequestedOrientation(
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.rose);
ImageButton b = (ImageButton) findViewById(R.id.imageButton1);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Dialog d1 = new Dialog(Rose.this);
d1.setContentView(R.layout.tariquet);
d1.setCanceledOnTouchOutside(true);
d1.show();
}
});
}
}
And my XML:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fitsSystemWindows="true"
android:isScrollContainer="true"
android:minHeight="1100dp"
android:minWidth="650dp">
<ImageView
android:src="#drawable/rose_tariquet"
android:id="#+id/imageView1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"></ImageView>
<Button android:text="X"
android:layout_height="wrap_content"
android:id="#+id/button1"
android:layout_width="55dp"
android:layout_gravity="right"></Button>
</FrameLayout>
public class CustomizeDialog extends Dialog implements OnClickListener {
Button close;
TextView tv;
public CustomizeDialog(Context context,String Stringcontent) {
super(context);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_diolog_main);
tv=(TextView) findViewById(R.id.content);
tv.setText(Stringcontent);
close = (Button) findViewById(R.id.close);
close.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v == close)
dismiss();
}
}
called:
CustomizeDialog customizeDialog = new CustomizeDialog(CustomDialog.this,"clickme");
customizeDialog.show();
I'm having problems using s.requestFocus() when s is a spinner. Is there a special treatment to get it to work when it's a spinner ?
Thanks
try this code..
spinner.setFocusable(true);
spinner.setFocusableInTouchMode(true);
I'm guessing you aren't literally just looking to "give focus" to the spinner. When you give focus to an EditText, the keyboard pops up, so you may be expecting the spinner selection to "open up" on focus - but it doesn't work that way (don't ask me why). Use s.performClick() to do this - it will act just as if the user clicked on the spinner control.

Spinner isn't focusable by default (source). So you have to make it focusable either in xml
<Spinner
android:id="#+id/spinner"
android:focusable="true"
android:layout_width="wrap_conten"
android:layout_height="wrap_content" />
or in code
findViewById(R.id.spinner).setFocusable(true);
