Trying to generate a simple pop-up

Trying to generate a simple pop-up - android

I am trying to generate a simple popup on click of a button, but due to some reason it is not working. Below is my code:
public class Product extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//overridePendingTransition(R.anim.fadein, R.anim.fadeout);
setContentView(R.layout.product);
String fontPath = "fonts/georgia.ttf";
Typeface tf = Typeface.createFromAsset(getAssets(), fontPath);
final Animation animScale = AnimationUtils.loadAnimation(this, R.anim.anim_scale);
Button Particle =(Button)findViewById(R.id.button1);
Button MDF=(Button)findViewById(R.id.button2);
Button Laminates=(Button)findViewById(R.id.button3);
Button Ply =(Button)findViewById(R.id.button4);
Button Floor=(Button)findViewById(R.id.button5);
Button Door=(Button)findViewById(R.id.button6);
Button EdgeBand=(Button)findViewById(R.id.button7);
Button ModFur=(Button)findViewById(R.id.button8);
Particle.setTypeface(tf);
MDF.setTypeface(tf);
Laminates.setTypeface(tf);
Ply.setTypeface(tf);
Floor.setTypeface(tf);
Door.setTypeface(tf);
EdgeBand.setTypeface(tf);
ModFur.setTypeface(tf);
/* Particle.startAnimation(animScale);
MDF.startAnimation(animScale);
Laminates.startAnimation(animScale);
Ply.startAnimation(animScale);
Floor.startAnimation(animScale);
Door.startAnimation(animScale);
EdgeBand.startAnimation(animScale);
ModFur.startAnimation(animScale); */
Particle.setOnClickListener(Par);
}
private View.OnClickListener Par = new View.OnClickListener(){
public void onClick(View v){
openNewDialog();
}
};
private void openNewDialog() {
new AlertDialog.Builder(this).setItems(R.array.pop,new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialoginterface,int i){
if(i==0){
Intent about = new Intent(Product.this,AboutUs.class);
startActivity(about);
}
if(i==1){
Intent about = new Intent(Product.this,AboutUs.class);
startActivity(about);
}
}});
}
In the Strings.xml file:

You need to call show() in order to actually display the dialog.
private void openNewDialog() {
new AlertDialog.Builder(this).setItems(R.array.pop,new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialoginterface,int i){
if(i==0){
Intent about = new Intent(Product.this,AboutUs.class);
startActivity(about);
}
if(i==1){
Intent about = new Intent(Product.this,AboutUs.class);
startActivity(about);
}
}}).show(); // Here
}

text color change on the basis of text selection :
text_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#00b200"></item>
<item android:state_focused="true" android:color="#00b200"/>
<item android:state_selected="true" android:color="#000000"/>
<item android:color="#d3d3d3"></item>
</selector>

Buttons Overlap

I made a stopwatch using chronometer with four buttons but when i use the visibility modes to make stop and pause button appear they overlap.... Pls explain why...Below is the code.....
Assume the layout file with buttons in relative layout...
public class StopWatchFragment extends Fragment {
Chronometer chronometer;
Button startStopWatch;
Button stopStopWatch;
Button resetStopWatch;
Button pauseStopWatch;
Button resumeStopWatch;
private long lastPause;
//RelativeLayout relativeLayout;
private int check = 0;
public StopWatchFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.stopwatch_layout,container,false);
chronometer = (Chronometer) rootView.findViewById(R.id.stopwatch);
startStopWatch = (Button) rootView.findViewById(R.id.startStopWatch);
stopStopWatch = (Button) rootView.findViewById(R.id.stopStopWatch);
resetStopWatch = (Button) rootView.findViewById(R.id.resetStopWatch);
pauseStopWatch = (Button) rootView.findViewById(R.id.pauseStopWatch);
resumeStopWatch = (Button) rootView.findViewById(R.id.resumeStopWatch);
relativeLayout = (RelativeLayout) rootView.findViewById(R.id.parentRelativeLayout);
pauseStopWatch.setVisibility(View.GONE);
//final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(relativeLayout.getLayoutParams());
startStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.start();
startStopWatch.setVisibility(View.GONE);
pauseStopWatch.setVisibility(View.VISIBLE);
if(check == 1){
resumeStopWatch.setClickable(true);
}
else{
resumeStopWatch.setClickable(false);
}
//params.setMargins(16,16,16,16);
//pauseStopWatch.setLayoutParams(params);
}
});
pauseStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
check = 1;
lastPause = SystemClock.elapsedRealtime();
chronometer.stop();
}
});
resumeStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(chronometer.getBase() + SystemClock.elapsedRealtime() - lastPause);
chronometer.start();
resumeStopWatch.setClickable(false);
}
});
stopStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.stop();
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
resumeStopWatch.setClickable(false);
}
});
resetStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.stop();
resumeStopWatch.setClickable(false);
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
}
});
return rootView;
}
}
This is the layout file pls refer for this....
<?xml version="1.0" encoding="utf-8"?>

This is the way buttons work when click on start button

You are hiding the button, but you are still listening with the OnClickListener. Try adding:
pauseStopWatch.setOnClickListener(null);
Then, when you make your button visible:
pauseStopWatch.setOnClickListener(whatever);

Try this layout
<?xml version="1.0" encoding="utf-8"?>

In the above, the pause button will be set to Gone. You make it visible later when user clicks start button

Simple, 1st need to create an newcustom_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView
android:layout_width="wrap_content"

android:text="You are 400pts. away from \n unlocking rewards. quit Earning?"
android:textSize="18dp"
android:textStyle="bold" />
</android.support.v7.widget.CardView>
</LinearLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/frmNo"
android:layout_marginRight="45dp"
android:layout_marginTop="75dp">
<android.support.design.widget.FloatingActionButton
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#android:color/transparent"
app:backgroundTint="#color/fab2" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:elevation="6dp"
android:text="No"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#android:color/white"

</FrameLayout>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/frmOk"
android:layout_marginLeft="50dp"
android:layout_marginTop="75dp">
<android.support.design.widget.FloatingActionButton
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#android:color/transparent"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:elevation="6dp"
android:text="Ok"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#android:color/white"
android:textStyle="bold" />
</FrameLayout>
</FrameLayout>
Then, in java file (in activity) paste this code
public class ViewDialog {
public void showDialog(Activity activity) {
final Dialog dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.newcustom_layout);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
FrameLayout mDialogNo = dialog.findViewById(R.id.frmNo);
mDialogNo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
FrameLayout mDialogOk = dialog.findViewById(R.id.frmOk);
mDialogOk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
dialog.cancel();
}
});
dialog.show();
}
}
Finally you can call it wherever you want.
ViewDialog alert = new ViewDialog();
alert.showDialog(CustomDialogActivity.this);

You can change your button by using
android:src=#drawable/image
You have to extends Dialog and implements OnClickListener
public class CustomDialogClass extends Dialog implements
android.view.View.OnClickListener {
public Activity c;
public Dialog d;
public Button yes, no;
public CustomDialogClass(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.custom_dialog);
yes = (Button) findViewById(R.id.btn_yes);
no = (Button) findViewById(R.id.btn_no);
yes.setOnClickListener(this);
no.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_yes:
c.finish();
break;
case R.id.btn_no:
dismiss();
break;
default:
break;
}
dismiss();
}
}
Call Dialog
CustomDialogClass cdd=new CustomDialogClass(Activity.this);
cdd.show();

Maybe try this method

Default pin lock screen layout

I want to provide lock screen, so every time user opens my app, he will be forced to enter pin. So I am looking for Android's default pin lock layout (as shown on image), which should work from Android 4.0. Can you tell me where to find layout of this or how to implement it properly?

I git below project from github and little changed it to provide a GUI like your image :
https://github.com/chinloong/Android-PinView
so create a project and in mainActivity insert this codes:
public class PinEntryView extends Activity {
String userEntered;
String userPin="8888";
final int PIN_LENGTH = 4;
boolean keyPadLockedFlag = false;
Context appContext;
TextView titleView;
TextView pinBox0;
TextView pinBox1;
TextView pinBox2;
TextView pinBox3;
TextView statusView;
Button button0;
Button button1;
Button button2;
Button button3;
Button button4;
Button button5;
Button button6;
Button button7;
Button button8;
Button button9;
Button button10;
Button buttonExit;
Button buttonDelete;
EditText passwordInput;
ImageView backSpace;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
appContext = this;
userEntered = "";
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main_layout);

note : userPin variable is your password and you can change it.
in below bock in activity class you should insert your code that you want execute if user enter correnct password (e.g start a new activity )
if (userEntered.equals(userPin))
{
statusView.setTextColor(Color.GREEN);
statusView.setText("Correct");
Log.v("PinView", "Correct PIN");
finish();
}
Note: add below line to main activity node in mainfist.xml file
android:theme="#android:style/Theme.NoTitleBar"
so your Activity node must be like :
<activity
android:name="com.example.MainActivity"
android:theme="#android:style/Theme.NoTitleBar"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

this is what the logcat shows

use
Context mContext = v.getApplicationContext();
instead of
Context mContext = getApplicationContext();
or
builder = new AlertDialog.Builder(StartMoving.this);
EDIT :
You are reading button
todo = (Button) findViewById(R.id.bgoto); <-----------
^^^^^
todo.setOnClickListener(this);

AlertDialog.Builder diag = new AlertDialog.Builder(this);
diag.setTitle("DIALOG TITLE")
.setMessage("YOUR MESSAGE")
.setCancelable(false)
.setNegativeButton("WHAT EVER THE BUTTON TEXT",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//enter code here
//do what ever the button in the dialog is clicked
dialog.cancel();
}
});
diag.show();
Easiest way to have a alert dialog
and dont forget to change the Button id in java to R.id.goto

if your are using alertDialog in TabHost then you have to write..
final AlertDialog alertDialog = new AlertDialog.Builder(**getParent()**).create();
//alertDialog.setTitle("Alert....");
alertDialog.setMessage("Your Text");
alertDialog.setButton("OK", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface arg0, int arg1)
{
finish();
}
});
alertDialog.show();

It seems that I've been reading the button from the Context and not from the alertDialog. The solution was to create a View that will be set as View for the AlertDialog and declare a button and set it as a child for the View.
final View view;
LayoutInflater inf = LayoutInflater.from(StartMoving.this);
view = inf.inflate(R.layout.rename, null);
final EditText newname = (EditText) view.findViewById(R.id.etNewRoomName);
final Button todo = (BUtton) view.findViewById(R.id.bTodo);
new AlertDialog.Builder(StartMoving.this)
.setView(view)
.setTitle("Rename")
.setMessage("Enter new name for room " + currentRoom)
.show();
