当我在左侧显示2文本视图时,一切正常。但是,当我在右侧显示2 textview时,我希望2 textview是右对齐的。但到目前为止,我还不能做到这一点。TextView.setGravity()
正在定义子视图的显示方式。您希望实际对齐textView,而不是其子项。您需要使用方法setLayoutParams()
请参阅。我不确定你想用包装器布局视图做什么。因此,下面的代码可能不是您所需要的全部。但这是将视图与相对布局对齐的推荐方法(实用)
如果第二个视图需要与countryName精确对齐,则可以使用以下选项:
View yourOtherView = findViewById(R.id.yourOtherView);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_BELOW, R.id.comment);
params.addRule(RelativeLayout.ALIGN_RIGHT, R.id.comment);
yourOtherView.setLayoutParams(params);
这会告诉它在注释视图下方对齐,然后右对齐。您可能需要对边距、填充和其他值进行调整,以使其完全正确
祝你好运
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if (row == null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.listitem_discuss, parent, false);
}

countryName = (TextView) row.findViewById(R.id.comment);
countryName.setText(coment.msgText);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
if(!coment.sentbyuser)
{
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);

countryName.setLayoutParams(params);
