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);
//Typeface xpressive=Typeface.createFromAsset(getAssets(), "fonts/XpressiveBold.ttf");
statusView = (TextView) findViewById(R.id.statusview);
passwordInput = (EditText) findViewById(R.id.editText);
backSpace = (ImageView) findViewById(R.id.imageView);
buttonExit = (Button) findViewById(R.id.buttonExit);
backSpace.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
passwordInput.setText(passwordInput.getText().toString().substring(0,passwordInput.getText().toString().length()-2));
}
});
buttonExit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Exit app
Intent i = new Intent();
i.setAction(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
appContext.startActivity(i);
finish();
}
}
);
//buttonExit.setTypeface(xpressive);
buttonDelete = (Button) findViewById(R.id.buttonDeleteBack);
buttonDelete.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (keyPadLockedFlag == true)
{
return;
}
if (userEntered.length()>0)
{
userEntered = userEntered.substring(0,userEntered.length()-1);
passwordInput.setText("");
}
}
}
);
titleView = (TextView)findViewById(R.id.time);
//titleView.setTypeface(xpressive);
View.OnClickListener pinButtonHandler = new View.OnClickListener() {
public void onClick(View v) {
if (keyPadLockedFlag == true)
{
return;
}
Button pressedButton = (Button)v;
if (userEntered.length()<PIN_LENGTH)
{
userEntered = userEntered + pressedButton.getText();
Log.v("PinView", "User entered="+userEntered);
//Update pin boxes
passwordInput.setText(passwordInput.getText().toString()+"*");
passwordInput.setSelection(passwordInput.getText().toString().length());
if (userEntered.length()==PIN_LENGTH)
{
//Check if entered PIN is correct
if (userEntered.equals(userPin))
{
statusView.setTextColor(Color.GREEN);
statusView.setText("Correct");
Log.v("PinView", "Correct PIN");
finish();
}
else
{
statusView.setTextColor(Color.RED);
statusView.setText("Wrong PIN. Keypad Locked");
keyPadLockedFlag = true;
Log.v("PinView", "Wrong PIN");
new LockKeyPadOperation().execute("");
}
}
}
else
{
//Roll over
passwordInput.setText("");
userEntered = "";
statusView.setText("");
userEntered = userEntered + pressedButton.getText();
Log.v("PinView", "User entered="+userEntered);

}
}
};
button0 = (Button)findViewById(R.id.button0);
//button0.setTypeface(xpressive);

}
#Override

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>

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....

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

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

here is my full code as you requested #mobie.. the Symptoms.java and the question.xml..dont matter the other code..just on the alert dialog that i asked.
Create Layout Like Below for Dialog Box : dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp" />
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="#+id/image"/>
<Button
android:id="#+id/dialogButtonOK"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Ok "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="#+id/image"
/>
</RelativeLayout>
Then, Where you want to place the Alert, Do like below
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Your Title");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Text");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

// TODO Auto-generated method stub
switch(arg1){

} }
There is no need to override onCheckedChanged() use following in your on savebutton click
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= (RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();
and now use radiovalue to store in database
Edit: forget (
rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();
try this
myRadioGrp=(RadioGroup)findViewById(R.id.RadioGroup01);
String radiovalue= ((RadioButton)this.findViewById(myRadioGrp.getCheckedRadioButtonId())).getText().toString();

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
}
I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity
