【问题描述】：
我有一个列表视图，我希望在左侧显示一些内容，在右侧显示其他内容： for example
表示内容的意思
getItem(position).getIsMO() == false
要显示在列表的左边。以及里面的内容
getItem(position).getIsMO() == true
显示在列表的右侧。
那部分的代码是：
public static class EfficientAdapter extends ArrayAdapter<Message>
implements Filterable {
private LayoutInflater mInflater;
// private Bitmap mIcon1;
private final Context context;
private final ArrayList<Message> values;
public EfficientAdapter(Context context, ArrayList<Message> values) {
// Cache the LayoutInflate to avoid asking for a new one each time.
super(context, R.layout.mycontent, values);
mInflater = LayoutInflater.from(context);
this.context = context;
this.values = values;
}
/**
* Make a view to hold each row.
*
* @see android.widget.ListAdapter#getView1(int, android.view.View,
* android.view.ViewGroup)
*/
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
// A ViewHolder keeps references to children views to avoid
// unneccessary calls
// to findViewById() on each row.
ViewHolder holder;
// When convertView is not null, we can reuse it directly, there is
// no need
// to reinflate it. We only inflate a new View when the convertView
// supplied
// by ListView is null.
if (convertView == null) {
convertView = mInflater.inflate(R.layout.mycontent, null);
holder = new ViewHolder();
if (getItem(position).getIsMO() == false) {
// parent.setPadding(0, 0, 15, 0);
// convertView.layout(15, 0, 0, 0);
holder.body = (TextView) convertView
.findViewById(R.id.body);
holder.date = (TextView) convertView
.findViewById(R.id.date);
holder.from = (TextView) convertView
.findViewById(R.id.from);
holder.status = (TextView) convertView
.findViewById(R.id.status);
} else {
// convertView.layout(0, 0, 15, 0);
// parent.setPadding(15, 0, 0, 0);
holder.body = (TextView) convertView
.findViewById(R.id.body);
holder.date = (TextView) convertView
.findViewById(R.id.date);
holder.from = (TextView) convertView
.findViewById(R.id.from);
holder.status = (TextView) convertView
.findViewById(R.id.status);
}
convertView.setTag(holder);
}
else {
// Get the ViewHolder back to get fast access to the TextView
// and the ImageView.
holder = (ViewHolder) convertView.getTag();
}
convertView.setOnClickListener(new OnClickListener() {
private int pos = position;
@Override
public void onClick(View v) {
Toast.makeText(context, "Click-" + pos, Toast.LENGTH_SHORT)
.show();
}
});
holder.body.setText(getItem(position).getBody());
holder.date.setText(getItem(position).getDate());
holder.from.setText(getItem(position).getPhoneNumber());
holder.status
.setText(String.valueOf(getItem(position).getStatus()));
/*
* if ("000".equals(getItem(position).getPhoneNumber())) { //
* convertView.setPadding(5, 0, 0, 0); // View layout =
* View.inflate(context, R.layout.mycontent, null); //
* layout.setPadding(5, 0, 0, 0);
* convertView.setLayoutParams(params); // parent.setPadding(5, 0,
* 0, 0); } else { // View layout = View.inflate(context,
* R.layout.mycontent, null); // layout.setPadding(0, 0, 5, 0);
* parent.setPadding(0, 0, 5, 0); // convertView.setPadding(0, 0, 5,
* 0); }
*/
return convertView;
}
static class ViewHolder {
TextView from;
TextView date;
TextView body;
TextView status;
}
}
问题是当我尝试parent.setPadding() 时，所有对象都在一侧的列表视图中对齐。
