Android Application Button onclicklistener

Android Application Button onclicklistener - java

Hi there i've been constructing this code for a week but i still cant get it to work. It has no errors but when i run it on the AVD it terminates suddenly.
package com.tryout.sample;
import java.util.Random;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.app.Activity;
public class MainActivity extends Activity implements View.OnClickListener{
Random number = new Random();
int Low = 1;
int High = 13;
int RandomNumber = number.nextInt(High-Low) + Low;
int current = 0;
int points=0;
final Integer[] cardid = { R.drawable.card1,
R.drawable.card10,
R.drawable.card11,
R.drawable.card12,
R.drawable.card13,
R.drawable.card2,
R.drawable.card3,
R.drawable.card4,
R.drawable.card5,
R.drawable.card6,
R.drawable.card7,
R.drawable.card8,
R.drawable.card9,
};
ImageView pic2 = (ImageView) findViewById(R.id.imageView1);
final TextView score = (TextView) findViewById(R.id.textView2);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView score = (TextView) findViewById(R.id.textView2);
Button high = (Button) findViewById(R.id.button1);
Button low = (Button) findViewById(R.id.button2);
final ImageView pic = (ImageView) findViewById(R.id.imageView1);
low.setOnClickListener(new view.OnClickListener() {
public void onClick(View v) {
int resource = cardid[RandomNumber];
if(current < RandomNumber){
points = points + 1;
score.setText(points);
pic.setImageResource(resource);
}else{
score.setText("Game Over");
}
}
});
high.setOnClickListener(new View.OnClickListener() {
public void higher(View v) {
int resource = cardid[RandomNumber];
if(current > RandomNumber){
points = points + 1;
score.setText(points);
pic.setImageResource(resource);
}else{
score.setText("Game Over");
}
}
});
int resource = cardid[RandomNumber];
pic.setImageResource(resource);
current = RandomNumber;
}
}
I cant figure out where my problem is, kindly check out my code. THanks for any help

put this:
ImageView pic2 = (ImageView) findViewById(R.id.imageView1);
final TextView score = (TextView) findViewById(R.id.textView2);
in you onCreate method after the call setContentView(R.layout.activity_main);.
How should R.id.imageView1 assigned if the content is not specified like in your case?
ImageView pic2;
TextView score;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pic2 = (ImageView) findViewById(R.id.imageView1);
score = (TextView) findViewById(R.id.textView2);

Working with writing and reading files in Android Studio

I am working on a side project in android studio and need to store some long term data to a file that can be written and readable, I am able to do this outside of android studio, but when I try to do it within, it sows a error saying
public void onClick(View v) 'onClick(View)' in 'Anonymous class derived from android.view.View.OnClickListener' clashes with 'onClick(View)' in 'android.view.View.OnClickListener'; overridden method does not throw 'java.io.FileNotFoundException'{
I have a function in a separate file that writes to a string from a file, but when I try to access that string from one of my main view pages, its asking for an exception, but will not work with said exception, I've tried try and catch but with no success

Here:
randomizeButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) throws FileNotFoundException {
What you are doing here: define an anonymous subclass of View.OnClickListener. And when you check the documentation for that class, it says:
public abstract void onClick (View v)
Now read the compiler message again you got. overridden method does not throw 'java.io.FileNotFoundException'
Thus the real answer here is: A) you have to understand what you are doing and B) you have to read compiler error messages really carefully.
Long story short, you can not override an inherited method and add checked exceptions such as FileNotFoundException to the signature of your method. So, the solution is to step back and to really learn/understand how exception handling works in Java. One possibility here: use try/catch in your readFile(), catch the FileNotFoundException and rethrow it as (unchecked) RuntimeException. Then you do not need to have throws FileNotFoundException on your method signatures, and the compiler won't complain any more.

Android Image Button to tic tac toe

Currently having an issue having an image button open to another activity when we try the app closes. What we are trying to create is a tic tac toe game that has a splash screen, main activity, and new activity that is the actual game. The splash screen opens to the main but when we try to open the main activity to the board game it closes on us. Any advice?
Here is the current code:

making the app searching for Bluetooth mac address and connect to it if available "Android Studio"

I'm not android studio developer or java developer but regarding for my graduation project I need to make an android app that connects to HC-05 Bluetooth module "Arduino", then starts to transmit and receive bytes ... I have found a lot of projects that connects to the Bluetooth module by showing you a list of Bluetooth devices then you can choose which one you want to connect ...
but I don't want to use this method I want to find a method that searches for a specific Bluetooth mac address and if it available, start connecting to it, if it not available, the app will continue searching ...
I don't have any experience how can programmatically make this.
so please be patient :D
I have done the XML design...
I want to add the mac address connecting code here

cannot find symbol method onActivityResult(int,int,Intent)

Im following the tutorial of In-app Billing from the following link:
Android Studio Google Play In-app Billing Tutorial.
Im implementing this logic in a Contact Adapter class which extends Base Adapter. In tutorial it is implemented in a class which extends Activity.
Error comes on onActivityResult(). I read several questions on this and I understand this method should be written in class which extends Activity but in my case the scenario is different.
Is there any way to solve this without writing onActivityResult method in MainActivity class.. and if not what should I do?

I recommend you to create an activity just to process this payment and then you can back to your normal flow.

In this way, there are a list of videos in the playlist, each video will start automatically when the first is finished. I need to click each video in the wall for start it

You can add an onClickListener to the ImageViews in the ImageWallView.java class, something like this:
for (int col = 0; col < numberOfColumns; col++) {
for (int row = 0; row < numberOfRows; row++) {
int elementIdx = getElementIdx(col, row);
if (images[elementIdx] == null) {
ImageView thumbnail = new ImageView(context);
thumbnail.setLayoutParams(new LayoutParams(imageWidth, imageHeight));
images[elementIdx] = thumbnail;
unInitializedImages.add(elementIdx);
thumbnail.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ImageWallView.this.context.startActivity(YouTubeIntents.createPlayVideoIntentWithOptions(
ImageWallView.this.context, (String)v.getTag(), true, false));
}
});
}
addView(images[elementIdx]);
}
}
Then you will need to add the video id as the tag in YouTubeThumbnailView in VideoWallActivity.java
Hope that helps

You can use ImageView OnClickListener as suggested in previous answer: (onSizeChanged in ImageWallView.java)
for (int col = 0; col < numberOfColumns; col++) {
for (int row = 0; row < numberOfRows; row++) {
int elementIdx = getElementIdx(col, row);
if (images[elementIdx] == null) {
ImageView thumbnail = new ImageView(context);
thumbnail.setLayoutParams(new LayoutParams(imageWidth, imageHeight));
images[elementIdx] = thumbnail;
unInitializedImages.add(elementIdx);
thumbnail.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ImageWallView.this.context.startActivity(YouTubeIntents.createPlayVideoIntentWithOptions(
ImageWallView.this.context, (String)v.getTag(), true, false));
}
});
}
addView(images[elementIdx]);
}
}
Then you need to store video id to the calling view of ImageWallView . (set and get tag is also used to store objects between views).
To get the child view of ImageWallView, use imageWallView.getChildAt(index). index is the position of ImageView which is clicked on ImageWallView. to get this index, use getElementIdx(col,row). You need to make this method public in ImageWallView.java.
EDITED
To use the Video ID of current thumbnail, Store the VideoID in onFlipped event. This is because onThumbnailLoaded the VideoID of next thumbnail available which immediately get Flipped and available on IamgeWallView. As VideoID is not available in onFlipped event, use it from onThumbnailLoaded event
Here it is:
Declare below string in class
private String strThumbnailVideoId;
set VideoID in onThumbnailLoaded event (in VideoWallActivity.java) into strThumbnailVideoId. This video ID will be of next thumbnail which will be flipped.
#Override
public void onThumbnailLoaded(YouTubeThumbnailView thumbnail, String videoId) {
nextThumbnailLoaded = true;
strThumbnailVideoId = videoId;
if (activityResumed) {
if (state.equals(State.LOADING_THUMBNAILS)) {
flipNext();
} else if (state.equals(State.VIDEO_FLIPPED_OUT)) {
// load player with the video of the next thumbnail being flipped in
state = State.VIDEO_LOADING;
player.cueVideo(videoId);
}
}
}
Now set the strThumbnailVideoId in onFlipped as a ImageWallView tag.
#Override
public void onFlipped(FlippingView view) {
imageWallView.showImage(flippingCol, flippingRow);
flippingView.setVisibility(View.INVISIBLE);
imageWallView.getChildAt(imageWallView.getElementIdx(flippingCol, flippingRow)).setTag(strThumbnailVideoId);
