每次按下按钮时,我都需要从 ListView 中的 cm1 和 cm2 行输出数据。行应显示在各种 TextView 中。
代码 TEST.java:
public String cm1;
public String cm2;
public class TEST extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MyList = (ListView) this.findViewById(R.id.listStrings);
setListAdapter();
// button
Button setup = (Button) this.findViewById(R.id.send);
setup.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
cm1 = "cm1text";
cm2 = "cm2text";
//xxxx
}
});
}
// adapter
private void setListAdapter() {
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.row //idknow what im must writehere to set cm1 string to cm1text tv
List.setAdapter(adapter);
}
代码 TEST.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/listStrings"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="@+id/send"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Send" />
</LinearLayout>
代码row.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/cm1tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/cm2tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
单击 2 次后应查看 ListView:
cm1
cm2
cm1
cm2
