安卓——家庭记账本4
今天完成了支出记录页面的编写,并对数据库插入信息。
首先打开软件进入主界面
下面的两个按钮设置为两个onClick事件
<ImageButton android:id="@+id/main_btn_more" android:layout_width="50dp" android:layout_height="50dp" android:src="@mipmap/more" android:layout_alignParentRight="true" android:layout_alignParentBottom="true" android:layout_margin="20dp" android:background="@drawable/main_morebtn_bg"/> <Button android:id="@+id/main_btn_edit" android:layout_width="100dp" android:layout_height="50dp" android:layout_alignBottom="@id/main_btn_more" android:background="@drawable/main_record_bg" android:layout_toLeftOf="@id/main_btn_more" android:text="@string/editone" android:textStyle="bold" android:textColor="@color/white" android:drawableLeft="@mipmap/edit" android:gravity="center_vertical"/>
public void onClick(View view){ switch (view.getId()){ case R.id.main_iv_search: Intent it = new Intent(this,SearchActivity.class); startActivity(it); break; case R.id.main_btn_edit: Intent it1 = new Intent(this,RecordActivity.class); startActivity(it1); break; case R.id.main_btn_more: MoreDialog moreDialog = new MoreDialog(this); moreDialog.show(); moreDialog.setDialogSize(); break; case R.id.item_mainlv_top_tv_budget: showBudgetDialog(); break; }
}
在MainActivity中建立onClick方法，完成点击事件并进行跳转。通过id寻找对应按钮。
接下来，在数据库中定义方法，将数据传入数据库
/* * 读取数据库当中的数据，写入内存集合 * kind 表示收入或支出 * */ public static List<TypeBean> getTypeList(int kind){ List<TypeBean> list = new ArrayList<>(); //读取typetb表中的数据 String sql = "select * from typetb where kind = "+kind; Cursor cursor = db.rawQuery(sql,null); //循环读取图标内容，存储到对象 while(cursor.moveToNext()){ String typename = cursor.getString(cursor.getColumnIndex("typename")); int imageId = cursor.getInt(cursor.getColumnIndex("imageId")); int simageId = cursor.getInt(cursor.getColumnIndex("simageId")); int kind1 = cursor.getInt(cursor.getColumnIndex("kind")); int id = cursor.getInt(cursor.getColumnIndex("id")); TypeBean typeBean = new TypeBean(id,typename,imageId,simageId,kind); list.add(typeBean); } return list; }
/* * 向记账表插入一条元素 * */ public static void insertItemToAccounttb(AccountBean bean){ ContentValues values = new ContentValues(); values.put("typename",bean.getTypename()); values.put("simageId",bean.getSimageId()); values.put("beizhu",bean.getBeizhu()); values.put("money",bean.getMoney()); values.put("time",bean.getTime()); values.put("year",bean.getYear()); values.put("month",bean.getMonth()); values.put("day",bean.getDay()); values.put("kind",bean.getKind()); db.insert("accounttb",null,values); // Log.i("animee", "insertItemToAccounttb: ok!!!!!");这是我测试用的，用于检测数据是否传入数据库 }
做完这些之后，还要配置适配器，最后组装，然后该功能才能实现
配置Account的适配器
import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; import com.example.bookeep.R; import com.example.bookeep.db.AccountBean; import java.util.Calendar; import java.util.List; public class AccountAdapter extends BaseAdapter { Context context; List<AccountBean> mDatas; LayoutInflater inflater; int year,month,day; public AccountAdapter(Context context, List<AccountBean> mDatas) { this.context = context; this.mDatas = mDatas; inflater=LayoutInflater.from(context); Calendar calendar = Calendar.getInstance(); year = calendar.get(Calendar.YEAR); month=calendar.get(Calendar.MONTH)+1; day=calendar.get(Calendar.DAY_OF_MONTH); } @Override public int getCount() { return mDatas.size(); } @Override public Object getItem(int i) { return mDatas.get(i); } @Override public long getItemId(int i) { return i; } @Override public View getView(int i, View view, ViewGroup viewGroup) { ViewHolder holder = null; if(view==null){ view=inflater.inflate(R.layout.item_mainlv,viewGroup,false); holder=new ViewHolder(view); view.setTag(holder); }else { holder= (ViewHolder) view.getTag(); } AccountBean bean = mDatas.get(i); holder.typeIv.setImageResource(bean.getSimageId()); holder.typeTv.setText(bean.getTypename()); holder.beizhuTv.setText(bean.getBeizhu()); holder.moneyTv.setText("￥"+bean.getMoney()); if(bean.getYear()==year && bean.getMonth()==month && bean.getDay()==day){ String time = bean.getTime().split(" ")[0]; holder.timeTv.setText("今天"+time); }else { holder.timeTv.setText(bean.getTime()); } return view; } class ViewHolder{ ImageView typeIv; TextView typeTv,beizhuTv,timeTv,moneyTv; public ViewHolder(View view){ typeIv=view.findViewById(R.id.item_mainlv_iv); typeTv=view.findViewById(R.id.item_mainlv_tv_title); timeTv=view.findViewById(R.id.item_mainlv_tv_time); beizhuTv=view.findViewById(R.id.item_mainlv_tv_beizhu); moneyTv=view.findViewById(R.id.item_mainlv_tv_money); } } }
设置监听，与适配器进行组装

做完这些之后，记录支出功能基本完成。
今天测试的时候，在模拟器上程序一直显示停止运行，最后通过Logcat得知在设置监听的时候有个方法错误，我把它注释掉就奇迹般地能运行了，这个方法是AS自动生成的，所以以后尽量少让其自动生成方法。
明天将会完成收入功能及其他功能。
