I have ask a question before about change method OnClick to method lifecycle
But I think the problem was solving.
But in this new question is same with before but different.
Now i have ask how add alertdialog to my source code. I have 3 aletdialog will show when the noise until 70 dB , 80 dB and 100 dB.
Here's MY CODE

You have an error in yours if conditions
if (dB >= 70 || dB <80){
//do something
}
else if (dB >=80 || dB <100){
//do something
}
e.g db=95 the app will go to the first if
the correct code is:
if (dB >= 70 && dB <80){
//do something
} else if (dB >=80 && dB <100){
//do something
}else{
//do something
}
so

I do not understand why last contact is added to the first card in recyclerview again when activity is resumed. I know that it is to do with cursor or content resolver.
Here is the java class with which I have problem.
while retreiving contacts again on onResume, last contact is re-added on first card in recycler view

Here is what I found which is adding one more item in your list
Try removing:
if (contactsObject != null) {
contactsArrayList.add(contactsObject);
Log.e("object added : ", contactsObject.getName);
}
Hope this helps.
Hi I want to open a activity when a if statement comes true. like "if gameStatus are equal to 12, then open scoreActivity". The Code:

The activity that i want to open will show to the player his score. the activity is equal to all game modes, there will be some test to the app understant what path should go on. test like this one:
"
if (gameStatus == 12) {
gameScore = gameScore*55;
TextView scoreText = (TextView) findViewById(R.id.textView8);
scoreText.setText(gameScore);
}
else if (gameStatus == 15){
"
There are 4 game modes: This is the 6x4 game, where we can find 24 cards (12 images).
else if (gameStatus == 15){
Intent intent = new Intent(Game6x4Activity.this, NextActivity.class);
startActivity(intent);
}
I think, you are asking for this. You can pass value to another activity with
intent.putExtra("key",desired value);
I have a Listview. I want to order it such that when new item added they add at top. I try
Collections.reverse(ListElementsArrayList);
And it works. But after (second,third click,....) it mix all earlier item.Is this possible. If yes help me.

Just use
List.add(0, element)
to add an element as first element of a list. As described in the documentation.
I am trying to use a code snipit from here:
http://www.androidsnippets.com/prompt-engaged-users-to-rate-your-app-in-the-android-market-appirater
When the code is put into my app I have this:
package com.example.beerportfoliopro;

if (prefs.getBoolean("dontshowagain", false)) { return ; }
SharedPreferences.Editor editor = prefs.edit();
// Increment launch counter
long launch_count = prefs.getLong("launch_count", 0) + 1;
editor.putLong("launch_count", launch_count);
// Get date of first launch
Long date_firstLaunch = prefs.getLong("date_firstlaunch", 0);

}

ll.setOrientation(LinearLayout.VERTICAL);
TextView tv = new TextView(mContext);
tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
tv.setWidth(240);
tv.setPadding(4, 0, 4, 10);
ll.addView(tv);
Button b1 = new Button(mContext);
b1.setText("Rate " + APP_TITLE);
b1.setOnClickListener(new View.OnClickListener() {

}
});

}
});
ll.addView(b2);
Button b3 = new Button(mContext);
b3.setText("No, thanks");
b3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if (editor != null) {
editor.putBoolean("dontshowagain", true);
editor.commit();
}
dialog.dismiss();
}
});
ll.addView(b3);
dialog.setContentView(ll);
dialog.show();
}
}
// see http://androidsnippets.com/prompt-engaged-users-to-rate-your-app-in-the-android-market-appirater
I imported all the libraries needed but am getting a few errors at this piece of code:
// Wait at least n days before opening
if (launch_count >= LAUNCHES_UNTIL_PROMPT) {
if (System.currentTimeMillis() >= date_firstLaunch +
(DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000)) {
showRateDialog(mContext, editor);
}
}
The error is at > and at the )) on this line:
(DAYS_UNTIL_PROMPT * 24 * 60 * 60 * 1000))
the first error says:
Cannot resolve symbol 'gt'
and the second error is:
';'expected unexpected token
Not sure what is wrong since it was taken straight from the snipit.
Replace > with >
> got encoded for display on a webpage as > but didn't get unencoded when you copied the code.
i have a problem in this application(Mini4WD Lap Timer) in my Motorola Defy.. they provide they source code.. maybe you could help me to be compatible it on my device..
https://play.google.com/store/apps/details?id=com.pimentoso.android.laptimer&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5waW1lbnRvc28uYW5kcm9pZC5sYXB0aW1lciJd
the problem is when calibrating, it stock..
and the small preview in the upper-left of the timer is not working, only shows black..
here is the codes
