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);
        }
    };
}
