很多人都说：我不知道我自己想要什么。其实这句话的真正含义是：我没有勇气面对和足够的努力去争取我想要的。

TextView、EditText、密码EditText、RadioButton、Button、Spinner、CheckBox、ToggleButton

1、工程目录

2、Test_changyongzujian.java

package com.example.test_changyongzujian;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;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;import android.widget.ToggleButton;public class Test_changyongzujian_Activity extends Activity {private Button cancelButton, registerButton;private EditText usernameEdit, passwordEdit;private RadioButton maleRadio, femaleRadio;private ToggleButton marrigeToggle;private CheckBox readingCheck, swimmingCheck;private Spinner positionSpinner;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.test_changyongzujian);usernameEdit = (EditText) findViewById(R.id.username);passwordEdit = (EditText) findViewById(R.id.password);maleRadio = (RadioButton) findViewById(R.id.male);femaleRadio = (RadioButton) findViewById(R.id.female);marrigeToggle = (ToggleButton) findViewById(R.id.marriged);readingCheck = (CheckBox) findViewById(R.id.reading);swimmingCheck = (CheckBox) findViewById(R.id.swimming);// SpinnerpositionSpinner = (Spinner) findViewById(R.id.position);String[] str = { "CEO", "CFO", "PM" };ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item, str);positionSpinner.setAdapter(aa);// ButtoncancelButton = (Button) findViewById(R.id.cancel);registerButton = (Button) findViewById(R.id.register);registerButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubBundle b = new Bundle();b.putString("username", "用户名称："+ usernameEdit.getText().toString());b.putString("password", "用户密码："+ passwordEdit.getText().toString());if (maleRadio.isChecked())b.putString("gender", "性别：男");else if (femaleRadio.isChecked())b.putString("gender", "性别：女");String temp = "爱好：";if (readingCheck.isChecked()) {temp += "阅读";} else if (swimmingCheck.isChecked()) {temp += " 游泳";}b.putString("hobby", temp);if (marrigeToggle.isChecked())b.putString("marrige", "婚否：已婚");elseb.putString("marrige", "婚否：未婚");b.putString("position", positionSpinner.getSelectedItem().toString());Intent intent = new Intent(Test_changyongzujian_Activity.this,Result.class);intent.putExtra("data", b);startActivity(intent);}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.test_changyongzujian_, menu);return true;}}

3、Result.java

package com.example.test_changyongzujian;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.ListView;public class Result extends Activity {private ListView listview;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.result);listview = (ListView) findViewById(R.id.listview01);// 获取上个页面传递过来的值Intent intent = this.getIntent();Bundle b = intent.getBundleExtra("data");List list = new ArrayList();list.add(b.getString("username"));list.add(b.getString("password"));list.add(b.getString("gender"));list.add(b.getString("hobby"));list.add(b.getString("marrige"));list.add(b.getString("position"));// listview设置适配器ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_checked, list);listview.setAdapter(adapter);}}

4、test_changyongzujian.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >

              android:text="注册" />        </TableRow>    </TableLayout></LinearLayout>

5、result.xml

<?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" >    <ListView        android:id="@+id/listview01"        android:layout_width="wrap_content"        android:layout_height="wrap_content" >    </ListView></LinearLayout>

6、AndroidMenifest.xml

需要添加Result.java的Activity
