android listVIew添加长按响应事件

============================（一）=========================

listview.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {

menu.setHeaderTitle("菜单");

menu.add(0, 0, 0,"添加" );

menu.add(0, 1, 0,"删除");

}

});

============================（二）=========================

registerForContextMenu(lv);

================================================================

1.在activity的onCreate(...)方法中为一个view注册上下文菜单

registerForContextMenu(lv);

2.在onCreateContextMenuInfo(...)中生成上下文菜单。

/*创建上下文菜单*/

@Override

public void onCreateContextMenu(ContextMenu menu, View v,

ContextMenuInfo menuInfo) {

super.onCreateContextMenu(menu, v, menuInfo);

menu.add(0, 1, 1, "删除");

}

3.在onContextItemSelected(...)中响应上下文菜单项。

/*设置上下文菜单点击事件*/

@Override

public boolean onContextItemSelected(final MenuItem item) {

final AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();

if(item.getItemId()==1){

new AlertDialog.Builder(this) //新建对话框

.setTitle("警告")

.setMessage("确定要删除么？")

.setIcon(R.drawable.plugin_notice) //设置图标

.setPositiveButton("确定", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

db.deleteNote(String.valueOf(info.id)); //删除数据库中该项内容

refreshListView(); //刷新listview

}

})

.setNegativeButton("取消", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

}

})

.show();

}

return super.onContextItemSelected(item);

}
