我正在開發一個android應用程序。如何用RelativeLayout以編程方式設置textview的引力?
public class MyListAdapter extends BaseAdapter {
Context con;
private LayoutInflater layoutinf;
ArrayList<Boolean> itemChecked = new ArrayList<Boolean>();
ArrayList<String> items_ = new ArrayList<String>();
public MyListAdapter(ChatActivity context) {
con = context;
}
public int getCount() {
return item_id.size();
}
public Object getItem(int position) {
return item_id.size();
}
public long getItemId(int position) {
return item_id.get(position).hashCode();
}
public View getView(final int position, View arg1, ViewGroup arg2) {
View v = arg1;
ViewHolder holder = null;
if (v == null) {
layoutinf = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = layoutinf.inflate(R.layout.row_chat, null);
holder = new ViewHolder();
// holder.tv_contact = (TextView) v.findViewById(R.id.phone_num);
holder.tv_sms_body = (TextView) v.findViewById(R.id.msg_body);
holder.tv_time = (TextView) v.findViewById(R.id.time);
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
if(item_flag.get(position).equals("1"))
{
holder.tv_sms_body.setBackgroundResource(R.drawable.bubble_green);
}
else if(item_flag.get(position).equals("0"))
{
holder.tv_sms_body.setBackgroundResource(R.drawable.bubble_yellow);
}
//holder.tv_contact.setText("" + item_phone_num.get(position));
holder.tv_sms_body.setText(item_msg_body.get(position));
holder.tv_time.setText(item_time.get(position));
return v;
}
}
佈局文件如下::我通過虛報行如下移植ListView
<RelativeLayout 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">
<TextView
android:id="@+id/msg_body"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignRight="@id/phone_num"
android:layout_below="@id/phone_num"
android:text="SMS"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/time"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@id/msg_body"
android:text="time"
android:textSize="12dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
如何設置TextView的權重編程在上面的代碼中使用的RelativeLayout ???
你想在TextView的文本有重力的權利,或TextViews的佈局有佈局重心嗎? – NameSpace
我希望TextView的佈局具有重力權。 – user3381979
