I am trying to create a word search using a gridview but I'm unsure how to add rows from a JSONArray, but my app keeps crashing at this point and also at gridView.addView(tableRow);
This is my new puzzle class

The problem is you cannot addView(view) directly to GridView, because it is an AdapterView which does not allow that. So you have to do this operation in your Adapter. You just have to add more data to the adapter and after call notifyDataSetChanged() on the adapter, so your GridView will be added the View by itself.

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);
The rows are coming in reverse order. It should be Monday then Tuesday then WednesdayI have a gridview which dynamically fetches data of current week(i.e monday to today). I am facing two issues.
1) My gridView elements are not arranged properly.
2) GridView shows data of that day also whose data does not exists. It simply copies all previous row values. I know rearrangement problem is because of resetPosition variable not getting updated. but if i update it, i get NullPointerException. How can i get rid of these problems?

hi dear here I am posting my whole class where I am getting problem. First I explain my problem. I am generating an arrayList "Items" using spinners and the elements in spinners and arrays are exactly same then After comparing array length and ArayList size I want to jump on next activity but problem is occoured in comparing arrays now please help me for this problem
Thanks here is my activity

public void onBackPressed()
{
// code here to show dialog
super.onBackPressed(); // optional depending on your needs
Intent intn = new Intent(AddItem.this,Exmain.class);
startActivity(intn);
}
}
and the major problem occured in this code which is array indexOutOfBound
for(int j = 0 ; j < arrayRecipe.length ; j++)
{
for(int i = 0 ; i <Items.size() ; i++)
{
if((arrayRecipe[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
if ((arrayRecipe2[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
if ((arrayRecipe3[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
}
}
thanks again for helping me
array.Length() always count from 1 not form zero use
arrayRecipe.length -1 in your for loop
Use This
for(int j = 0 ; j < (arrayRecipe.length)-1 ; j++)
{
for(int i = 0 ; i <Items.size() ; i++)
{
if((arrayRecipe[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
if ((arrayRecipe2[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
if ((arrayRecipe3[i].equals(Items.get(j))))
{
subset.add(true);
break;
}
}
}
Two problems:
You're using the size of arrayRecipe to bound the index of arrayRecipe, arrayRecipe2 and arrayRecipe3 All three arrays are different in size, hence leading to your error. You need 3 different for loops, one for each arrayRecipe.
Your i and j are in the wrong places.
Items.get(j) should be Items.get(i) as you are using Items.size to limit the size of i. Likewise, arrayRecipe.get(i) should be arrayRecipe.get(j).
Also, it is true that getLength() and getSize() start counting from 1 rather than 0 so the index of the final slot is (getLenght() - 1), but by using < as the clause in your for loop handles that.
I have two TextView, two EditText and two Buttons. I want to set a DialogBox or Toast when the button is clicked without entering any values in the textview. I have two stings, s and s1. If s and s1 or either s or s1 is not entered in the edittext, I must get a toast. I wrote a code for toast but it's not working fine!
Can you help me with this?

Change your validation to this :
if((s.equals("")) && (s1.equals("")))
{
Toast.makeText(getBaseContext(),"cnt b empty" ,Toast.LENGTH_SHORT).show();
}
Or you can check like this:
if((s.length() == 0) && (s1.length() == 0))
{
Toast.makeText(getBaseContext(),"cnt b empty" ,Toast.LENGTH_SHORT). show();
}
Tried your code and validation is working :

Try if (s.isEmpty() || s1.isEmpty()) to check if your strings are empty. == and .equals will not work with string comparison because they are comparing the objects and not solely the contents. To check if two strings are equal, you can use firstString.compareTo(anotherString) == 0.
Trim your edittext value then compare
if((("").equals(s.trim())) && (("").equals(s1.trim())))
{
Toast.makeText(getBaseContext(),"cnt b empty" ,Toast.LENGTH_SHORT).show();
