1.RadioButton 、 CheckBox

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="fill_parent"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <RadioButton
            android:id="@+id/femaleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="female" />

        <RadioButton
            android:id="@+id/maleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="male" />
    </RadioGroup>

    <CheckBox
        android:id="@+id/swim"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="swim" />

    <CheckBox
        android:id="@+id/run"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="run" />

    <CheckBox
        android:id="@+id/read"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="read" />

</LinearLayout>

private RadioGroup genderGroup = null;
    private RadioButton femaleButton = null;
    private RadioButton maleButton = null;
    private CheckBox swimBox = null;
    private CheckBox runBox = null;
    private CheckBox readBox = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        genderGroup = (RadioGroup) findViewById(R.id.genderGroup);
        femaleButton = (RadioButton) findViewById(R.id.femaleButton);
        maleButton = (RadioButton) findViewById(R.id.maleButton);

        swimBox = (CheckBox) findViewById(R.id.swim);
        runBox = (CheckBox) findViewById(R.id.run);
        readBox = (CheckBox) findViewById(R.id.read);

        genderGroup
                .setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

                    @Override
                    public void onCheckedChanged(RadioGroup group, int checkedId) {
                        if (femaleButton.getId() == checkedId) {
                            System.out.println("famale");
                            Toast.makeText(MainActivity.this, "famale",
                                    Toast.LENGTH_SHORT).show();//弹出提示
                        } else if (maleButton.getId() == checkedId) {
                            System.out.println("male");
                        }
                    }
                });

        swimBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                if (isChecked) {
                    System.out.println("swim is checked");
                } else {
                    System.out.println("swim is unchecked");
                }
            }
        });

        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment()).commit();
        }
    }

2.进度条ProgressBar

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.mars_1000_control02.MainActivity"
    tools:ignore="MergeRootFrame" >

    <ProgressBar
        android:id="@+id/firstBar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:visibility="gone" />

    <ProgressBar
        android:id="@+id/secondBar"
        style="?android:attr/progressBarStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone" />

    <Button
        android:id="@+id/myButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="begin" />

</LinearLayout>

public class MainActivity extends Activity {
private ProgressBar firstBar = null;
private ProgressBar secondBar = null;
private Button myButton = null;
private int i = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

firstBar = (ProgressBar) findViewById(R.id.firstBar);
secondBar = (ProgressBar) findViewById(R.id.secondBar);
myButton = (Button) findViewById(R.id.myButton);
myButton.setOnClickListener(new ButtonListener());
System.out.println(firstBar.getMax());
}

class ButtonListener implements OnClickListener {
@Override
public void onClick(View v) {
if (i == 0) {
firstBar.setVisibility(View.VISIBLE);
secondBar.setVisibility(View.VISIBLE);
} else if (i < 100) {
firstBar.setProgress(i);//设置进度
//firstBar.setSecondaryProgress(i + 10);//设置第二进度
secondBar.setProgress(i);
} else {
firstBar.setVisibility(View.GONE);
secondBar.setVisibility(View.GONE);
}
i+=10;
}

}

3.列表控件ListView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    tools:context="com.example.mars_1000_control02.Activity02"
    tools:ignore="MergeRootFrame" >

    <LinearLayout
        android:id="@+id/listLinearLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <ListView
            android:id="@id/android:list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:drawSelectorOnTop="false"
            android:scrollbars="vertical" >
        </ListView>
    </LinearLayout>

</LinearLayout>

public class Activity02 extends ListActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activity02);

ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map1 = new HashMap<String, String>();
HashMap<String, String> map2 = new HashMap<String, String>();
HashMap<String, String> map3 = new HashMap<String, String>();
map1.put("user_name", "zhangsan");
map1.put("user_ip", "192.168.0.1");
map2.put("user_name", "lisi");
map2.put("user_ip", "192.168.0.2");
map3.put("user_name", "wangwu");
map3.put("user_ip", "192.168.0.3");
list.add(map1);
list.add(map2);
list.add(map3);
SimpleAdapter listAdapter = new SimpleAdapter(this, list,
R.layout.user, new String[] { "user_name", "user_ip" },
new int[] { R.id.user_name, R.id.user_ip });
setListAdapter(listAdapter);
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
System.out.println("id------------" + id);
System.out.println("position------" + position);
}
