Need help with Andriod

UPDATE: So I've completed all the mockups in PS and did the flow for the app activities... however i have a question.. Should i use a splash page or not? even though its a social app..

you could display a splash screen if your main activity needs to do stuff in the background before its contents are displayed in a view. you could use an indeterminate progress bar that you hide when the result can be displayed.

If you dont have anything to load the a splash is counter productive. Thats just my preference though.

You are making a social app. So you have tones of stuff to load. So i dont think you need a timed splash screen.

android:columnWidth="90dp"
android:numColumns="auto_fit"

******************************************
HelloGridView.java



import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.GridView;
import android.widget.Toast;


public class HelloGridView extends ActionBarActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));

gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(HelloGridView.this, "" + position, Toast.LENGTH_SHORT).show();
}
});
}
}
***************************************


ImageAdapter.java


import android.content.Context;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;

public class ImageAdapter extends BaseAdapter {
private Context mContext;

public ImageAdapter(Context c) {
mContext = c;
}

public int getCount() {
return mThumbIds.length;
}

public Object getItem(int position) {
return null;
}

public long getItemId(int position) {
return 0;
}

// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_ CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}

imageView.setImageResource(mThumbIds[position]);
return imageView;
}

// references to our images
private Integer[] mThumbIds = {
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7
};
}

..this an example of wat i'm trying to achieve except it will be 4 columns instead of 3 as in the pic below

works for me. just had to change this android:numColumns="auto_fit" to android:numColumns="4" because my screen fits 3 columns

[Satanforce]

works for me. just had to change this android:numColumns="auto_fit" to android:numColumns="4" because my screen fits 3 columns

But why diid the auto fit work? Will a 4 column look good in landscape mode? Couldn't he just have changed up the android:columnWidth?

[wiel]

not sure what he is trying to do. since android:numColumns="auto_fit" worked, the images are probably in the wrong folder or they don't exist. if you just need 4 columns or if you don't want to ignore the width of the items I would use numcolumns
