我在db中使用了数据，并在listview中显示了每一行，我给了sms按钮转到smsactivity，但是单击sms按钮时，它并没有进入任何激活状态，只是在那里，没有显示任何错误或logcat错误
这是我的activity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_item2);
mDbHelper = new GinfyDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());
}
@SuppressLint("NewApi")
@SuppressWarnings("deprecation")
private void fillData() {
mDbHelper.open();
Cursor projectsCursor = mDbHelper.fetchAllProjects();
//startManagingCursor(projectsCursor);
// Create an array to specify the fields we want to display in the list (only TITLE)
String[] from = new String[]{GinfyDbAdapter.CATEGORY_COLUMN_TITLE,GinfyDbAdapter.CATEGORY_COLUMN_CONTENT,GinfyDbAdapter.CATEGORY_COLUMN_COUNT};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.text2,R.id.text1,R.id.count};
dataAdapter = new SimpleCursorAdapter(
this, R.layout.activity_row2,
projectsCursor,
from,
to,
0);
setListAdapter(dataAdapter);
EditText myFilter = (EditText) findViewById(R.id.myFilter);

我正在使用simpleadapter从db中获取数据，之后是按钮功能，我正在使用customadapter从listview中获取数据，类customadapter extper SimpleCursorAdapter
在这里，我也提到了我的xml文件。
<LinearLayout
android:id="@+id/Share"
android:layout_width="0.0dip"
android:layout_height="fill_parent"
android:layout_weight="1.0"
android:background="@drawable/button_new_feed"
android:orientation="horizontal" >
<Button
android:id="@+id/buttonsms"
android:layout_width="25.0dip"
android:layout_height="fill_parent"
android:layout_marginLeft="4.0dip"
android:src="@drawable/sms" />
<ImageButton
android:id="@+id/mail"
android:layout_width="25.0dip"
android:layout_height="fill_parent"
android:layout_marginLeft="6.0dip"
android:src="@drawable/mail" />
</LinearLayout>
最佳答案
很难找出出了什么问题
您有这个和CustomAdapter。 activity_row2中的行项目已经膨胀了。
dataAdapter = new SimpleCursorAdapter(
this, R.layout.activity_row2,
projectsCursor,
from,
to,
0);
您已经定义了
CustomAdapter，但是从不使用它。String[] from = new String[]{GinfyDbAdapter.CATEGORY_COLUMN_TITLE,GinfyDbAdapter.CATEGORY_COLUMN_CONTENT,GinfyDbAdapter.CATEGORY_COLUMN_COUNT};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.text2,R.id.text1,R.id.count};
dataAdapter = new CustomAdapter (YourPrayerActivity .this, R.layout.activity_row2, projectsCursor, from, to);
还要如下更改您的CustomAdapter
class CustomAdapter extends SimpleCursorAdapter {
private LayoutInflater mInflater;
@SuppressWarnings("deprecation")
public CustomAdapter(Context context, int layout, Cursor c, String[] from, int[] to)
{
super(context, layout, c, from, to);
mInflater= LayoutInflater.from(context);
Toast.makeText(YourPrayerActivity.this, "text", 1000).show();
// TODO Auto-generated constructor stub
}
@Override
public void bindView(View view, Context context, final Cursor cursor){
int row_id = cursor.getColumnIndex("_id"); //Your row id (might need to replace)
TextView tv = (TextView) view.findViewById(R.id.text1);
final TextView tv1 = (TextView) view.findViewById(R.id.text2);
int col1 = cursor.getColumnIndex("title");
String title = cursor.getString(col1 );
int col2 = cursor.getColumnIndex("content");
final String content = cursor.getString(col2 );
tv.setText( title);
tv1.setText( content);
Button button = (Button) view.findViewById(R.id.buttonsms);
button.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
Log.i("....................",""+cursor.getCount());
Toast.makeText(YourPrayerActivity.this, "text",400000).show();
}
});
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent){
LayoutInflater inflater = LayoutInflater.from(context);
View v = inflater.inflate(R.layout.activity_row2, parent, false);
bindView(v,context,cursor);
return v;
}
}
关于java - 我的动态 ListView 的每一行中的按钮不起作用？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/18123443/
