編輯:關於Android編程
思路I :通過二維數據放我們需要的城市地區 ,第一個spinner加載第一級城市,監聽第一級城市去控制第二個spinner加載二級城市。
代碼如下:
MainActivity
package com.example.testdiqu; import java.util.ArrayList; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.Spinner; import android.widget.AdapterView.OnItemSelectedListener; public class MainActivity extends ActionBarActivity { private Spinner parent,chaird; private ArrayListlist=new ArrayList ();//城市 private ArrayList clist=new ArrayList ();//子城市 private String [][] citys=new String[][]{ {濟南市,歷下區,市中區,槐蔭區,天橋區,歷城區,長清區,平陰縣,濟陽縣,商河縣,章丘市}, {青島市,市南區,市北區,四方區,黃島區,崂山區,李滄區,城陽區,膠州市,即墨市,平度市,膠南市,萊西市}, {淄博市,淄川區,張店區,博山區,臨淄區,周村區,桓台縣,高青縣,沂源縣}, {棗莊市,薛城區,峄城區,台兒莊區,山亭區,滕州市}, {東營市,東營區,河口區,墾利縣,利津縣,廣饒縣}, {濰坊市,濰城區,寒亭區,坊子區,奎文區,臨朐縣,昌樂縣,青州市,諸城市,壽光市,安丘市,高密市,昌邑市}, {煙台市,芝罘區,福山區,牟平區,萊山區,長島縣,龍口市,萊陽市,萊州市,蓬萊市,招遠市,棲霞市,海陽市}, {威海市,環翠區,文登市,榮成市,乳山市}, {濟寧市,任城區,微山縣,魚台縣,金鄉縣,嘉祥縣,汶上縣,泗水縣,梁山縣,曲阜市,兖州市,鄒城市}, {泰安市,泰山區,岱岳區,寧陽縣,東平縣,新泰市,肥城市}, {日照市,東港區,岚山區,五蓮縣,莒縣}, {萊蕪市,萊城區,鋼城區}, {臨沂市,蘭山區,羅莊區,沂南縣,郯城縣,沂水縣,蒼山縣,費縣,平邑縣}, {德州市,德城區,寧津縣,慶雲縣,臨邑縣,齊河縣,平原縣,夏津縣,武城縣,樂陵市,禹城市,莒南縣,蒙陰縣,臨沭縣}, {聊城市,東昌府區,陽谷縣,莘縣,茌平縣,東阿縣,冠縣,高唐縣,臨清市}, {濱州市,濱城區,惠民縣,陽信縣,無棣縣,沾化縣,博興縣,鄒平縣}, {菏澤市,牡丹區,曹縣,單縣,巨野縣,定陶縣,成武縣,郓城縣,鄄城縣,東明縣} }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); parent=(Spinner)findViewById(R.id.parent); chaird=(Spinner)findViewById(R.id.chaird); loadData(); } private void loadData() { // TODO Auto-generated method stub for(int i=0;i adapter=new ArrayAdapter (MainActivity.this, android.R.layout.simple_spinner_item, list); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); parent.setAdapter(adapter); parent.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView parent, View view, int position, long id) { // TODO Auto-generated method stub clist.clear();//清除數據 for(int j=1;j adapter=new ArrayAdapter (MainActivity.this, android.R.layout.simple_spinner_item, clist); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); chaird.setAdapter(adapter); } @Override public void onNothingSelected(AdapterView parent) { // TODO Auto-generated method stub } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } }
前言在學習Android內存性能優化時,發現需要對Android系統的內存概況得有個概況了解,便有了此篇文章。這篇文章僅僅介紹相關於內存的,即輔助理解 官方文檔 How
主要的類: package de.hdodenhof.circleimageview; import edu.njupt.zhb.main.
本博客目的:仿知乎首頁向上滑動時動畫隱藏Toolbar、FlocationActionButton、Tab導航,下滑時顯示,如果和你的期望不同,那麼你可以不需要看了,免的
Android性能的優化主要分為兩點1、布局優化2、內存優化布局優化首先來看一下布局優化,系統在渲染UI的時候會消耗大量的資源,所以,對布局的優化就顯得尤為重要避免Ove
