android - try to add setonitemclicklistener to gridview and get a mistake

I am new to Android and I'm trying to add setOnItemClickListener to my gridview and i am getting the following error:
setOnItemClickListener in AdapterView cannot by applied to MainActivity
for this code line: grid.setOnItemClickListener(this);
What am I doing wrong? Could you help me please?

The setOnItemClickListener method does not take in the context as an argument, it takes in an OnItemClickListener object. What you need to do is pass in a new OnItemClickListener in the method call and then override the OnItemClick method.
Example:
grid.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> adapter, View v, int position,
long arg3)
{
//code to be executed on click
}
I hope this answers your question.

GridView is not shown in an example with Navigation Drawer

I've downloaded the Navigation Drawer example from the developers guide, I try to implement a GridView into an Activity of one of the options of the Drawer, but in execution time the GridView doesn't appears, the IDE doesn't show me any errors and in an example apart I can do it de GridView successfuly, How do I correct this problem?
My code is here:
In the MainActivity I use the same like the example with
Fragment fragment;
FragmentManager fragmentManager;
fragment = new inicioFragment(R.layout.inicio);
fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

public class InicioActivity extends Activity {
TextView tv1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.inicio);
tv1=(TextView)findViewById(R.id.tv1);
GridView gv = (GridView)findViewById(R.id.gridView1);
gv.setAdapter(new ImageAdapter(this.getApplicationContext()));
gv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id){
String g=Integer.toString(position);
tv1.setText(g);
}
});
}
}

Thanks for your collaboration!!

Try to change InicioActivity into a fragment.
And check this question. I think you are facing the same problem.

The following worked for me. In Android Studio:
1) Create a new Navigation Drawer Activity from the list of activity templates.
2) Note that several layout files will be created for you, including a content_main.xml. Replace the XML in the content_main.xml file with your <GridView> XML.
3) Create the relevant XML files or Java classes for the GridView, eg. the ImageAdapter class and an XML file for the GridView item layout.

You can use fragment,
http://developer.android.com/guide/components/fragments.html
this page have a example, maybe can help you.

Create a global variable to get the position of Slider(Let suppose that variable be pos).Now in getView of your slider adapter code like this
public View getView(final int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(cont);
pos=position;
imageView.setImageResource(Imgid[position]);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(80, 70));
imageView.setBackgroundResource(GalItemBg);
return imageView;
}
Now on button click code like this:
btnNextScreen.setOnClickListener(new View.OnClickListener() {
private int position;
public void onClick(View v) {
// TODO Auto-generated method stub
//Intent nextScreen = new Intent(Main.this, OpenImage.class);
Intent nextScreen=new Intent(getApplicationContext(),OpenImage.class);
//Sending data to another Activity
nextScreen.putExtra("id",Imgid[pos]);
Log.e("n", Imgid[pos]);
startActivity(nextScreen);
}
});

Just pass the selected image id value in the Gallery on click listener.
topsgallery.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long arg3)
{
// TODO Auto-generated method stub
Intent fullImage = new Intent(YourActivity.this,FullImageView.class)
fullImage.putExtra("image_url",R.drawable.image);
startActivity(fullImage);
}
});
consider the following steps :
#1 Create a new activity say for ex : FullImageView with the following view and declare that in manifest.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/android" />
</ImageView>
</LinearLayout>
3 : Receive the intent in onCreate of FullImageView activity
ImageView image = (ImageView) findViewById(R.id.image);
int image_link = getIntent().getIntExtra("image_url", R.drawable.default);
4 : Set the URL to your ImageView.
imageView.setImageResource(image_link);
Please feel free if you face any issues regarding this.

You can put the intent inside the adapter... and then do something like this (Note that you need to pass the context to the adapter):
public View getView(final int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(cont);
imageView.setImageResource(Imgid[position]);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(80, 70));
imageView.setBackgroundResource(GalItemBg);
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent nextScreen=new Intent(context,OpenImage.class);
nextScreen.putExtra("image",ImgId[pos]);
startActivity(nextScreen);
}
});
return imageView;
}

Please Help me guys

Hi there just have a look at CustomArrayAdapter used for ListViews and Gridviews especially point 10 at this Tutoiral there you get to know how to customize your GridView/ListView (handled same way)
This might also help
If you have problems with the hotrizontal way, try this project: https://github.com/jess-anders/two-way-gridview

Place single image in multiple places without creating imageview

Lat me know if this post is of any help :)

you can do like this
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv = new ImageView(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50; params.topMargin = 60;
rl.addView(iv, params);
and then add this r1 in your main view then again change margin, height and other param and add again like this you do n no of times

Do you try include tag for it?
img.xml
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_home"/>
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<include layout="#layout/img"/>
<include layout="#layout/img"/>
<include layout="#layout/img"/>
<include layout="#layout/img"/>
</LinearLayout
