我想显示标签,我在这个列宽度中使用网格视图相同,但我不想根据我要显示的文本保持列宽相同。我可能会尝试这个。 我想显示如下图所示的文字如何实现
public class MainActivity extends Activity {
Imagehelper controller;
EditText mAutoSearch;
ArrayList<String> selContactList = new ArrayList<String>();
SimpleStringAdapter adapter;
GridView gridView;
private Button save;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAutoSearch = (EditText) findViewById(R.id.et_autoComplete);
save = (Button) findViewById(R.id.save);
gridView = (GridView) findViewById(R.id.grid);
adapter = new SimpleStringAdapter(this, 0, selContactList);
gridView.setAdapter(adapter);
save.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String item = mAutoSearch.getText().toString();
selContactList.add(item);
adapter.setNewList(selContactList);
mAutoSearch.setText("");
}
});
}
public class SimpleStringAdapter extends BaseAdapter {
Context activity;
// public ArrayList<String> list;
Typeface normaltypeface;
LayoutInflater layoutinflator;
public SimpleStringAdapter(Context context, int textViewResourceId,
ArrayList<String> selContactList) {
// TODO Auto-generated constructor stub
activity = context;
// list = locations;
layoutinflator = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void setNewList(ArrayList<String> selContactList) {
// list = objects;
this.notifyDataSetChanged();
}
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = layoutinflator.inflate(R.layout.gridview, null);
holder.desc_tv = (TextView) convertView
.findViewById(R.id.genderdesc);
holder.imgbtn = (ImageButton) convertView
.findViewById(R.id.imageButton1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
String gender = getItem(position);
holder.desc_tv.setText(gender);
holder.imgbtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String s = getItem(position);
System.out.println("String item position: " + s);
notifyDataSetChanged();
}
});
return convertView;
}
class ViewHolder {
TextView desc_tv;
ImageButton imgbtn;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getCount() {
return selContactList.size();
}
@Override
public String getItem(int position) {
return selContactList.get(position);
}
}
}
我的主要xml是:
<LinearLayout 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"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:orientation="horizontal"
android:weightSum="1" >
<EditText
android:id="@+id/et_autoComplete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_margin="10dp"
android:layout_weight="1"
android:hint="Search"
android:paddingBottom="10dp"
android:paddingTop="10dp" />
<Button
android:id="@+id/save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="Save" />
</LinearLayout>
<GridView
android:id="@+id/grid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:columnWidth="90dip"
android:gravity="center"
android:horizontalSpacing="5dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="5dp" >
</GridView>
</LinearLayout>
我的gridview xml是:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

<Button
android:id="@+id/save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>
我希望布局看起来像下面的一样。
我怎样才能实现它?
