android textview adapter,通过Adapter动态添加TextView

通过Adapter根据类对象的里的数组属性的长度为LinearLayout动态加载TextView，使用BaseAdapter

基本功能：右侧显示Name，左侧排列显示value[]

item_list_view.xml:

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="horizontal">

android:layout_width="80dp"

android:layout_height="wrap_content"

android:id="@+id/name_textView"

/>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/textLinearLayout"

android:orientation="vertical">

创建一个SerialClass：我想实现左侧显示key，右侧对应多个values的情况，但不知道其他有什么合适的工具，查了下List、Map都不行，也可能可以用但我不知道(如果有知道的老师，望告知，谢谢)。

类包含两个变量：一个String name，另一个是数组String[] snValue

下面是代码：

public class SerialClass {

private String name;

private String[] snValue;

public SerialClass(){};

public SerialClass(String _name, String[] _snValue) {

this.name = _name;

this.snValue = _snValue;

}

public String getName() {

return name;

}

public String[] getSnValue() {

return snValue;

}

public void setName(String _name) {

this.name = _name;

}

public void setSnValue(String[] _snValue) {

this.snValue = _snValue;

}

}

MyAdapter:为LinearLayout动态添加TextView

public class MyAdapter extends BaseAdapter {

private SerialClass[] data;

private Context context;

private static final String ACTIVITY_TAG = "MyAdapter";

public MyAdapter(Context _context,SerialClass[] _data) {

this.context = _context;

this.data = _data;

}

@Override

public int getCount() {

return data.length;

}

public View getView(int position, View convertView, ViewGroup parent) {

View view = LayoutInflater.from(context).inflate(R.layout.item_list_view,null);

TextView nameView = (TextView) view.findViewById(R.id.name_textView);

nameView.setText(data[position].getName());

LinearLayout linearLayout = (LinearLayout) view.findViewById(R.id.textLinearLayout);

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);

for(int i=0;i

TextView valueView = new TextView(context);

valueView.setText(data[position].getSnValue()[i]);

valueView.setLayoutParams(layoutParams);

linearLayout.addView(valueView);

}

String msg = "" + data[position].getSnValue().length;//int转String

Log.i(ACTIVITY_TAG,msg);

return view;

}

public long getItemId(int position) {

return 0;

}

public Object getItem(int position) {

return null;

}

}

MainActivity:

public class MainActivity extends AppCompatActivity {

private Context context;

private SerialClass[] snData = new SerialClass[3];

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

context = MainActivity.this;

String[] str01 = {"0f:12:22:a1:ee"};

String[] str02 = {"test01","test02","test03"};

String[] str03 = {"str2","str1"};

for(int i=0;i

snData[i] = new SerialClass();

}

snData[0].setName("mac:");

snData[0].setSnValue(str01);

snData[1].setName("sn:");

snData[1].setSnValue(str02);

snData[2].setName("android_id:");

snData[2].setSnValue(str03);

ListView listView = (ListView) findViewById(R.id.list_view);

MyAdapter myAdapter = new MyAdapter(context,snData);

listView.setAdapter(myAdapter);

}

}

activity_main:

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/list_view />
