我已经知道如何在Android的gridView中添加String，但是我想添加textviews来格式化文本（重力，颜色等）。这是我当前的代码：
GridView gridView = (GridView) findViewById(R.id.grades);
ArrayList<TextView> display = new ArrayList<TextView>();
ArrayAdapter<TextView> adapter = new ArrayAdapter<TextView>(this,
android.R.layout.simple_list_item_1, display);
gridView.setAdapter(adapter);
for(int i = 0; i<currentClass.grades.size(); i++)
{
TextView name = new TextView(this);
TextView weight = new TextView(this);
TextView cur_points = new TextView(this);
TextView total_points = new TextView(this);
TextView cur_percent = new TextView(this);
name.setText(currentClass.grades.get(i).name);
weight.setText(currentClass.grades.get(i).weight);
cur_points.setText(currentClass.grades.get(i).cur_points);
total_points.setText(currentClass.grades.get(i).total_points);
cur_percent.setText(currentClass.grades.get(i).cur_percent);
name.setTextColor(Color.WHITE);
weight.setTextColor(Color.WHITE);
cur_points.setTextColor(Color.WHITE);
total_points.setTextColor(Color.WHITE);
cur_percent.setTextColor(Color.WHITE);
name.setSingleLine(true);
weight.setSingleLine(true);
cur_points.setSingleLine(true);
total_points.setSingleLine(true);
cur_percent.setSingleLine(true);
name.setGravity(Gravity.LEFT);
weight.setGravity(Gravity.RIGHT);
cur_points.setGravity(Gravity.RIGHT);
total_points.setGravity(Gravity.RIGHT);
cur_percent.setGravity(Gravity.RIGHT);
display.add(name);
display.add(weight);
display.add(cur_points);
display.add(total_points);
display.add(cur_percent);
adapter.notifyDataSetChanged();
}
不幸的是，当我运行它时，gridview只是给了我每个TextView的信息：“ android.id.widget.TextView（{42f20a88等}。
如何将textview添加到gridView？
像这样尝试一下
gridview.xml
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gridView1"
android:numColumns="auto_fit"
android:gravity="center"
android:columnWidth="100dp"
android:stretchMode="columnWidth"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</GridView>
item.xml
<TextView
android:id="@+id/grid_item_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:layout_marginTop="5px"
android:textSize="15px" >
</TextView>
自定义适配器类的textView
public class TextViewAdapter extends BaseAdapter {
private Context context;
private final String[] textViewValues;
public TextViewAdapter(Context context, String[] textViewValues) {
this.context = context;
this.textViewValues = textViewValues;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.item, null);
// set value into textview
TextView textView = (TextView) gridView
.findViewById(R.id.grid_item_label);
textView.setText(textViewValues[position]);
} else {
gridView = (View) convertView;
}
return gridView;
}
@Override
public int getCount() {
return textViewValues.length;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
}
然后，最后在主类中设置适配器
gridView.setAdapter(new TextViewAdapter(this, YOUR_ARRAY_WITH_TEXT_FOR_TEXTVIEWS));
还请注意，您可以传递任何其他值，例如文本的颜色和构造函数中的另一个参数，然后像...
textView.setColor(textViewColors[position]);
对于所有textview具有共同点的属性，您只能更改item.xml :)我希望它对您有所帮助。
