安卓实验报告

安卓实验报告班级：xxxxx学号：11111111姓名：xxxx实验一：Activity生命周期的测试一：实验目的掌握使用Eclipse开发Android应用开发程序的方法；掌握Android虚拟设备的创建方法；了解Android的程序结构；了解使用命令行创建Android程序方法；了解Activity生命周期，理解Activity事件回调，onRestoreInstanceState()和onSaveInstanceState两个函数的使用。

二：实验设备Eclipse 开发Android 应用Android虚拟设备（ AVD）三：实验内容（1）正常启动ActivityLife，然后单击用户界面的“结束程序”按钮关闭程序。

（2）正常启动ACtivityLife，然后通过“拨号键”启动内置的拨号程序，再通过“回退建”退出拨号程序，使ActivityLife重新显示在屏幕中。

二：实验设备Eclipse 开发Android 应用Android虚拟设备（ AVD）三：实验内容要求写一个自我介绍的安卓应用，包括姓名，性别，爱好，其中性别用radioButton选项编写，点击提交时，姓名，性别，爱好会在下面显示出来。

四：实验核心代码：public class MainActivity extends Activity {private EditText editText1;private EditText editText2;private EditText editText3;private TextView textView1;private TextView textView2;private TextView textView3;private RadioGroup radioGroup;private RadioButton radioButton1;private RadioButton radioButton2;private Button button;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(yout.activity_main);editText1 = (EditText) findViewById(R.id.e1);editText2 = (EditText) findViewById(R.id.e2);textView1 = (TextView) findViewById(R.id.t1);textView2 = (TextView) findViewById(R.id.t2);textView3 = (TextView) findViewById(R.id.t3);radioGroup = (RadioGroup) findViewById(R.id.RadioGroup1);radioButton1 = (RadioButton) findViewById(R.id.RadioButton1);radioButton2 = (RadioButton) findViewById(R.id.RadioButton2);button = (Button) findViewById(R.id.button1);radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(RadioGroup arg0, final int arg1) { button.setOnClickListener(new View.OnClickListener() {public void onClick(View arg0) {String str = editText1.getText().toString().trim();String str1 = editText2.getText().toString().trim();textView1.setText("姓名："+str);textView3.setText("爱好："+str1);if (arg1 == R.id.RadioButton1)textView2.setText("性别："+"男");else if (arg1 == R.id.RadioButton2)textView2.setText("性别："+"女");}});}});}五：运行结果截图：实验三：不同界面的切换一：实验目的掌握各种界面布局的特点和使用方法；掌握选项菜单，子菜单和快捷菜单的使用方法。
