新增月份管理页面,将新增账本移植到这个页面
主页面视图
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:gravity="center"> <TextView android:gravity="center" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="40sp" android:text="@string/month" /> <View android:layout_width="fill_parent" android:layout_marginTop="10dp" android:layout_height="1dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:background="#aa000000" /> <ListView android:id="@+id/l_month" android:layout_width="match_parent" android:layout_height="560dp" /> <ImageButton android:id="@+id/add" android:onClick="addAccount" android:layout_width="120dp" android:layout_height="120dp" android:scaleType="centerInside" android:layout_centerHorizontal="true" android:background="#00FF0000" android:src="@drawable/img" android:layout_below="@+id/list_view" /> </LinearLayout>
列表视图的元件
<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="80dp" android:id="@+id/month" android:layout_marginLeft="20dp" android:layout_alignParentLeft="true" android:gravity="center" android:singleLine="true" android:textSize="30sp" android:ellipsize="marquee" android:text="costTitle"> </TextView>
页面视图适配代码
package com.example.myapplication; import android.annotation.SuppressLint; import android.database.Cursor; import android.database.sqlite.SQLiteDatabase; import android.os.Bundle; import android.os.Message; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ImageButton; import android.widget.ListView; import android.widget.AdapterView; import androidx.annotation.Nullable; import androidx.appcompat.app.AppCompatActivity; import android.content.Intent; import java.util.ArrayList; import java.util.List; import android.os.Handler; public class monthActivity extends AppCompatActivity { List<String> list; private ImageButton Add; private DBHelper helper; private ListView listView; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.month); Add=findViewById(R.id.add); listView=findViewById(R.id.l_month); iniView(); } @SuppressLint("Range") private void iniView() { helper=new DBHelper(monthActivity.this); list=new ArrayList<>(); SQLiteDatabase db=helper.getReadableDatabase(); Cursor cursor=db.query("account2",null,null,null,null, null,null); while (cursor.moveToNext()){ String mon=cursor.getString(cursor.getColumnIndex("Date")).substring(0,7); if(!find(mon)) { list.add(mon); } } db.close(); } public void addAccount(View view){//跳转 Intent intent=new Intent(monthActivity.this,new_cost.class); //noinspection deprecation startActivityForResult(intent,1); } public boolean find(String a) { boolean flag=false; for (String str : list) { if(str.equals(a)) { flag=true; break; } } return flag; } @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); if(requestCode==1&&resultCode==1) { iniView(); } } }
这样我们基本所有的页面视图都完成了
