[英]Android layout: How to achieve this particular look?
我在使用Android布局時遇到困難,我感覺它一直在隨機捕捉/調整大小/移動。 我正在嘗試實現這種特殊的布局,但是我不知道如何。
任何幫助/技巧,以實現這種布局將不勝感激!
這是我嘗試過的代碼:
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) {
System.out.println(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;
int imgSize = 0;
if (convertView == null) {
WindowManager wm = (WindowManager) mContext
.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
Point size = new Point();
display.getSize(size);
imgSize = size.x / 4;
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(imgSize,
imgSize));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
imageView.setLayoutParams(new GridView.LayoutParams(imgSize * 2,
imgSize * 2));
imageView.setImageResource(mThumbIds2[0]);
return imageView;
}
// Keep all Images in array
public Integer[] mThumbIds = { R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic, R.drawable.yourpic,
R.drawable.yourpic, R.drawable.yourpic };
public Integer[] mThumbIds2 = { R.drawable.bigpicture };
}
在這里嘗試一些重要的事情:layout_span。 有了它,您可以在html表中執行colspan之類的操作
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_span="2"
android:src="@drawable/yourbigpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
</TableRow>
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
</TableRow>
<TableRow>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/yourpic" />
</TableRow>
