正確だと思う私のbuttonAdapterクラスは次のとおりです。
package com.example.test;
import android.content.Context;
import android.graphics.Color;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.GridView;
public class ButtonAdapter extends BaseAdapter {
private Context mContext;
public String [] fName = { "File 1", "File 2", "Roflcopters"};
// Gets the context so it can be used later
public ButtonAdapter(Context c) { mContext = c; }
// Total number of things contained within the adapter
public int getCount () { return 8; }
// Require for structure, not really used in my code.
public Object getItem (int position) { return null; }
// Require for structure, not really used in my code. Can be used to get the id of an item in the adapter for manual control.
public long getItemId (int position) { return position; }
public View getView (int position, View convertView, ViewGroup parent){
Button btn;
if (convertView == null) { // if it's not recycled, initialize some attributes
btn = new Button (mContext);
btn.setLayoutParams (new GridView.LayoutParams (190, 190));
btn.setPadding (1, 1, 1, 1);
} else {
btn = (Button) convertView;
}
// btn.setText(filesnames[position]);
// filenames is an array of strings
//btn.setTextColor (Color.WHITE);
//btn.setBackgroundResource (R.drawable.sample_2);
//btn.setBackgroundColor (Color.BLACK);
btn.setHighlightColor(Color.GREEN);
btn.setId (position);
return btn;
}
}
これが私のホームクラスです。onItemClick が機能しません。ここで何が間違っていますか:
package com.example.test;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
import android.widget.Toast;
public class home extends Activity implements OnItemClickListener {
public final static String EXTRA_MESSAGE1 = "com.example.text.MESSAGE";
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView (R.layout.activity_home);
GridView gridview = (GridView) findViewById (R.id.gridview);
gridview.setAdapter (new ButtonAdapter (this));
/*gridview.setOnItemClickListener (new OnItemClickListener () {
public void onItemClick (AdapterView <?> parent, View v, int position, long id) {
Toast.makeText (home.this, "" + position, Toast.LENGTH_LONG).show ();
Intent intent = new Intent (this, alarm.class);
String message = "Position:" + position;
intent.putExtra(EXTRA_MESSAGE1, message);
startActivity (intent);
}
});
* */
}
@Override
public void onItemClick (AdapterView <?> parent, View v, int position, long id) {
Intent intent = new Intent (this, alarm.class);
String message = "Position:" + position;
intent.putExtra(EXTRA_MESSAGE1, message);
startActivity (intent);
}
}
コメントアウトされておらず、「onItemClick」がコメントされている場合、onItemClick は機能せず、コメント化された「setOnItemClickListener」も機能しません。私は何を間違っていますか?
