一:第一步先创建一个项目,名字可以随便取但是首字母要大写
二:在项目里面我划线的地方进行编写代码
1:也可以在layout里面进行创建新的项目
点进去后点next
写完之后点击Finish就创建完成了
三:创建页面
1:先创建一个带有图片的页面
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:background="@drawable/ic_launcher"
- tools:context=".BarActivity" >
-
- </LinearLayout>
2:在创建一个可以登录或者注册的页面(这里我写的是注册系统)

3:在创建一个可以显示吐丝的页面
- <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:paddingBottom="@dimen/activity_vertical_margin"
- android:paddingLeft="@dimen/activity_horizontal_margin"
- android:paddingRight="@dimen/activity_horizontal_margin"
- android:paddingTop="@dimen/activity_vertical_margin"
- tools:context=".InfoActivity" >
-
- <TextView
- android:id="@+id/tv_show"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="@string/hello_world" />
-
- </RelativeLayout>

四:进行连接
1:找到第一个页面相对应得java代码段并书写代码和第二个(注册页面)进行连接
- package com.example.day5;
-
- import android.os.Bundle;
- import android.app.Activity;
- import android.content.Intent;
- import android.view.Menu;
-
- public class BarActivity extends Activity {
-
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_bar);
-
- Thread t = new Thread(new Runnable() {
-
- @Override
- public void run() {
- // TODO Auto-generated method stub
- try {
- Thread.sleep(3000);
- } catch (InterruptedException e) {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
- Intent it = new Intent(getApplicationContext(), MainActivity.class);
- startActivity(it);
- }
- });
- t.start();
- }
-
- }

2:第一个和第二个页面进行连接(找到第二个java代码段和上面一样)
- package com.example.day5;
-
- import android.os.Bundle;
- import android.app.Activity;
- import android.content.Intent;
- import android.view.View;
- import android.view.WindowManager;
- import android.view.View.OnClickListener;
- import android.widget.ArrayAdapter;
- import android.widget.Button;
- import android.widget.CheckBox;
- import android.widget.EditText;
- import android.widget.RadioButton;
- import android.widget.Spinner;
-
- public class MainActivity extends Activity implements OnClickListener {
- //1:定义id控件
- private EditText etusername,etpwd;
- private RadioButton rbM,rbW;
- private CheckBox cb1,cb2,cb3,cb4;
- private Button btnCommit,btnCancle;
- private Spinner spItem;
- String[] items = null;
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- //影藏状态栏
- getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
- //影藏标题栏
- getActionBar().hide();
- setContentView(R.layout.activity_main);
- // 2:找到id控件
- init();
- // 3:设置点击事件
- btnCommit.setOnClickListener(this);
- //准备数据
- //标题数据
- items = new String[]{"移动212","移动213","移动214","移动215"};
- //使用适配器来进行页面和数据的链接
- ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),
- R.layout.ilte,items);
- spItem.setAdapter(adapter);
- }
-
- private void init() {
- etusername = (EditText) findViewById(R.id.et_username);
- etpwd = (EditText) findViewById(R.id.et_pwd);
- rbM = (RadioButton) findViewById(R.id.rd_M);
- rbW = (RadioButton) findViewById(R.id.rd_W);
- cb1 = (CheckBox) findViewById(R.id.cb_1);
- cb2 = (CheckBox) findViewById(R.id.cb_2);
- cb3 = (CheckBox) findViewById(R.id.cb_3);
- cb4 = (CheckBox) findViewById(R.id.cb_4);
- btnCommit = (Button) findViewById(R.id.btn_Commit);
- btnCancle = (Button) findViewById(R.id.btn_Cancle);
- spItem = (Spinner) findViewById(R.id.sp_Item);
- }
-
- @Override
- public void onClick(View arg0) {
- //4:获取用户名
- String userName = etusername.getText().toString();
- //5:获取密码
- String pwd = etpwd.getText().toString();
- //6:获取性别单选
- String sex = "";
- if(rbM.isChecked()){
- sex = rbM.getText().toString();
- }
- if(rbW.isChecked()){
- sex = rbW.getText().toString();
- }
- //7:获取爱好
- String fav = "";
- if(cb1.isChecked()){
- fav += cb1.getText().toString();
- }
- if(cb2.isChecked()){
- fav += cb2.getText().toString();
- }
- if(cb3.isChecked()){
- fav += cb3.getText().toString();
- }
- if(cb4.isChecked()){
- fav += cb4.getText().toString();
- }
- //7.2获取下拉列表选中的内容
- int i = spItem.getSelectedItemPosition();
- String spItem = items[i];
- //8:传值跳转
- Intent it = new Intent(getApplicationContext(),InfoActivity.class);
- it.putExtra("userName",userName);
- it.putExtra("pwd",pwd);
- it.putExtra("sex",sex);
- it.putExtra("fav",fav);
- it.putExtra("spItem",spItem);
-
- startActivity(it);
- }
-
- }
![](https://csdnimg.cn/release/blogv2/dist/pc/img/newCodeMoreWhite.png)
2.2:这里有个下拉列表的字体和背景修改
- <?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="match_parent"
- android:textSize="20dp"
- android:textColor="#3fcc75" >
-
-
- </TextView>
3:第二个页面和第三个页面进行连接
- package com.example.day5;
-
- import android.os.Bundle;
- import android.app.Activity;
- import android.content.Intent;
- import android.view.Menu;
- import android.widget.TextView;
- import android.widget.Toast;
-
-
- public class InfoActivity extends Activity {
-
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_info);
-
- Intent it = getIntent();
-
- String userName = it.getStringExtra("userName");
- String pwd = it.getStringExtra("pwd");
- String sex = it.getStringExtra("sex");
- String fav = it.getStringExtra("fav");
- String spItem = it.getStringExtra("spItem");
-
- String str = userName + ":" + pwd + ":"+sex+":"+fav+":"+spItem;
-
- Toast.makeText(getApplicationContext(), str, 1).show();
-
- TextView tvShow = (TextView) findViewById(R.id.tv_show);
- tvShow.setText(str);
- }
-
-
-
- }

五:运行
六:这样就可以看到实现3个页面的跳转l
