Android 建立大量的test project 的管理方法，非常实用

在学习安卓时，可能会建立大量的test project 来测试各个组件，以更好的学习它。

但是为了验证学习每一种效果，会非常没必要，而且特别繁琐。

现在介绍的是两种管理方法：

一 通过手工的将 Activity 信息添加到一个ActivityManager中，

然后在启动Activity将注册的Activity信息，填充到一个ListView中。

主要有两个类。

ActivityManager， ActivityManager$ActivityInfo.

代码：

/**
* Created by mjz on 14-12-20.
*/
public class ActivityManager {
private static ActivityManager single = new ActivityManager();
private List<ActivityInfo> liAct;

private ActivityManager() {
liAct = new ArrayList<ActivityInfo>();
register();

}

public static ActivityManager getInstance() {
return single;
}

private void register() {
add(com.majunzhe.demos.te_and1.MainActivity.class,
com.majunzhe.demos.te_and1.MainActivity.class.getName());
add(MainActivity.class, MainActivity.class.getName());
add(MyTabActivity.class, "Bottom tabs");
add(AnimMainActivity.class, "Animation");
add(Arcs.class, "Arcs");
add(Sweep.class, "Sweep");
add(Game.class, "Game");
add(TeDemos.class, "Entry Manager");
}

public void add(Class act, String tag) {
ActivityInfo actInfo = new ActivityInfo(act, tag);
liAct.add(actInfo);
}

public ActivityInfo get(int index) {
return liAct.get(index);
}

public void remove(ActivityInfo act) {
liAct.remove(act);
}

public List getAll() {
return liAct;
}

public static class ActivityInfo {
String mTag;
Class<Activity> act;

public ActivityInfo(Class<Activity> act, String tag) {
this.act = act;
this.mTag = tag;
}

public Activity getActivity() {
return null;
}

public String getTag() {
return mTag;
}

public void start(Activity home) {
Intent intent = new Intent();
intent.setClass(home, act);
home.startActivity(intent);
}

@Override
public String toString() {
return mTag;
}
}
}

二 这个方法是在看 android apidemos是看到的，觉得较为方便，就重新实现了一遍。

在manifest文件中声明activity时，给每个activity添加一个android：label，将这个label做为路径，分类添加到listview中。

例如：

有四个acitvity，label分别是 a/b/c, a/d, e, f/g, h/i/j/k。

那么当我们打开启动Acitvity时，界面会显示

a

e

f

h

，

当点击 item a时，只会显示b，然后点击b，显示c，点击c，打开一个Activity。

我们遍历到的activity是通过给每个要启动的activity添加一个intent-filter来获取到的。

下面是主类的代码：

/**
* Created by mjz on 15-1-10.
*/
public class TeDemos extends Activity {

final static String TAG = "TeDemos";
final static String PACKAGE_PATH = "com.majunzhe.Path";
private String mCurPath;

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);

mCurPath = getIntent().getStringExtra(PACKAGE_PATH);
mCurPath = mCurPath == null ? "" : mCurPath;

ListView liView = (ListView) findViewById(R.id.entry_container);
SimpleAdapter adapter = new MyAdapter(this, getData(), R.layout.entry_list_item,
new String[]{"title"}, new int[]{R.id.entry_tv});
liView.setAdapter(adapter);
liView.setOnItemClickListener(listener);
}

private List getData() {
List datas = new ArrayList<Map<String, Object>>();

Intent intent = new Intent(IntentAction.DEMO_ACTION, null);
intent.addCategory(Intent.CATEGORY_SAMPLE_CODE);
PackageManager pm = getPackageManager();
List<ResolveInfo> liInfo = pm.queryIntentActivities(intent, 0);

Log.i(TAG, "getData() "+mCurPath);
if (null == liInfo) {
return datas;
}

Map entries = new HashMap<String, Object>();

for (int i = 0; i < liInfo.size(); ++i) {
ResolveInfo info = liInfo.get(i);
String label = info.loadLabel(pm).toString();
if (false == label.startsWith(mCurPath)) {
continue;
}
String paths[] = label.replace(mCurPath, "").split("/");
String nextLabel = paths[0];

if (paths.length == 1) {
addItem(datas, nextLabel, activityIntent(info.activityInfo.packageName, info.activityInfo.name));
} else if (entries.get(nextLabel) == null) {
entries.put(nextLabel, true);
addItem(datas, nextLabel, browseIntent(mCurPath +"/"+ nextLabel+"/"));
}
}
return datas;
}

private void addItem(List datas, String name, Intent intent) {
Map map = new HashMap<String, Object>();
map.put("title", name);
map.put("intent", intent);
datas.add(map);
}

private Intent activityIntent(String pkg, String cls) {
Intent intent = new Intent();
intent.setClassName(pkg, cls);
return intent;
}

private Intent browseIntent(String path) {
if(path.startsWith("/")){
path = path.substring(1);
}
Intent intent = new Intent();
intent.setClass(this, TeDemos.class);
intent.putExtra(PACKAGE_PATH, path);
return intent;
}

class MyAdapter extends SimpleAdapter {
public MyAdapter(Context context, List<Map<String, Object>> data, int resource, String[] from, int[] to) {
super(context, data, resource, from, to);
}
}

private AdapterView.OnItemClickListener listener = new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Map<String, Object> map = (Map<String, Object>)parent.getItemAtPosition(position);
Intent intent = (Intent)map.get("intent");
startActivity(intent);
}
};
}
