画像表示アプリケーションを作りたいのですが、画像をフルスクリーンで表示できません。SD カードから読み込むことはできますが、画像をクリックするとアプリケーションがクラッシュしました。誰でも私を助けることができますか?
これが私のコードです:
public class MainActivity extends Activity {
private ImageAdapter imageAdapter;
ArrayList<String> f = new ArrayList<String>();// list of file paths
ArrayList<Integer> resultList = getIntegerArray(f);
File[] listFile;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getFromSdcard();
GridView imagegrid = (GridView) findViewById(R.id.ImageGrid);
imageAdapter = new ImageAdapter();
imagegrid.setAdapter(imageAdapter);
imagegrid.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
i.putExtra("id", position);
startActivity(i);
}
});
私のFullImageActivity
public class FullImageActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_image);
// get intent data
Intent i = getIntent();
// Selected image id
int position = i.getExtras().getInt("id");
ImageAdapter imageAdapter = new ImageAdapter();
ImageView imageView = (ImageView) findViewById(R.id.full_image_view);
imageView.setImageResource(resultList.get(position));
}
}
