我已经知道如何将String添加到android的gridView中,但是我想添加textviews来格式化文本(重力,颜色等)。这是我目前的代码:
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等等}。
如何将textview添加到gridView?
解决方案使用类似的方法尝试它 $ b $ p gridview.xml
<?xml version =1.0encoding =utf-8?> < GridView xmlns:android =http: //schemas.android/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 15px> < / TextView>
textView自定义适配器类
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); 查看gridView; if(convertView == null){ gridView = new View(context); //从mobile.xml获取布局 gridView = inflater.inflate(R.layout.item,null); //将值设置为textview TextView textView =(TextView)gridView .findViewById(R.id.grid_item_label); textView.setText(textViewValues [position]); } else { gridView =(View)convertView; } 返回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,最后设置适配器您的主要类
pre $ gridView.setAdapter(new TextViewAdapter(this,YOUR_ARRAY_WITH_TEXT_FOR_TEXTVIEWS));还要注意,您可以传递任何其他值,如文本的颜色和构造函数中的另一个参数,然后设置它们在适配器中就像...
textView.setColor(textViewColors [position]);对于所有textview共有的属性,您只能更改item.xml :) $ b $希望它能帮助你......
I already know how to add String's to a gridView in android however I want to add textviews to format the text( Gravity, color, etc). This is my current code:
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(); }Unfortunately when I run it the gridview simply gives me the information of each TextView: "android.id.widget.TextView({42f20a88 and so on}.
How would I add textview's to a gridView?
解决方案try it with something like this
gridview.xml
<?xml version="1.0" encoding="utf-8"?> <GridView xmlns:android="schemas.android/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>
Custom adapter class for 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; } }and then , finally set adapter in your main class
gridView.setAdapter(new TextViewAdapter(this, YOUR_ARRAY_WITH_TEXT_FOR_TEXTVIEWS));also note that you can pass any other values like color of text and as another argument in constructor and then set them in adapter like ...
textView.setColor(textViewColors[position]);for attributes that all textview have in common you can change the item.xml only :) i hope it helped you ....
