我在 Android 屏幕上显示了一个 gridviewImages。我的要求是滑动全屏图像
这里我的代码:
图像适配器:
public class ImageAdapter extends BaseAdapter {
private Context mContext;
// Constructor
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) {
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;
}
// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.cn1, R.drawable.cn2,
R.drawable.cn3, R.drawable.cn4,
R.drawable.cn5, R.drawable.cn6,
R.drawable.cn7, R.drawable.cn8,
R.drawable.cn9, R.drawable.cn10,
R.drawable.cn11, R.drawable.cn12
};
}
主要活动:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
// Send intent to SingleViewActivity
Intent i =
new Intent(getApplicationContext(), SingleViewActivity.class);
// Pass image index
i.putExtra("id", position);
Log.d("onCreateMain>>","OnCreateMain");
startActivity(i);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
单视图活动:
public class SingleViewActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.single_view);
Log.d("onCreate>>","OnCreate");
// Get intent data
Intent i = getIntent();
// Selected image id
int position = i.getExtras().getInt("id");
Log.d("Position>>>","Position"+position);
ImageAdapter imageAdapter = new ImageAdapter(this);
ImageView imageView = (ImageView) findViewById(R.id.SingleView);
imageView.setImageResource(imageAdapter.mThumbIds[position]);
}
}
布局 XML 文件:
活动主.xml:
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>
单视图.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView android:id="@+id/SingleView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
