如何进行Android联机及模拟器单独测试Activity的辅助Activity示例开发

本篇文章为大家展示了如何进行Android联机及模拟器单独测试Activity的辅助Activity示例开发，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

想起写个单独测试Activity的辅助Activity的原因是在联机测试的时候IDEA或者Android Studio中的指定运行Activity功能没法使用了。

下面付IDE中指定运行Activity的界面截图：

辅助Activity要做的事情是将辅助Activity作为启动的默认Activity，其主界面中以ListView的形式展示所有Activity，通过单击ListView的Item项来启动要测试的Activity。

1. 辅助Activity代码示例：

package secondriver.app;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.content.pm.ActivityInfo;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView;import android.widget.ArrayAdapter;import android.widget.LinearLayout;import android.widget.ListView;import java.util.ArrayList;import java.util.Arrays;import java.util.List;/** * Created by Broncho on 2015/11/15. */public class TestActivitiesActivity extends Activity implements AdapterView.OnItemClickListener {    private LinearLayout mRootView;    private ListView mListView;    private ArrayAdapter mAdapter;    private List mAllActivities;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        initView();        mAllActivities = getActivities(this, this.getPackageName(), Arrays.asList(this.getClass()));        mAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, android.R.id.text1, mAllActivities);        mListView.setAdapter(mAdapter);        mListView.setOnItemClickListener(this);    }    private void initView() {        mRootView = new LinearLayout(this);        mListView = new ListView(this);        mListView.setId(android.R.id.list);        mRootView.addView(mListView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);        setContentView(mRootView);    }    @Override    public void onItemClick(AdapterView parent, View view, int position, long id) {        Class activity = mAllActivities.get(position);        //启动指定的Activity        startActivity(new Intent(this, activity));    }    /**     * 获取所有要测试的Activity Class     *     * @param context     * @param packageName     * @param excludeActivities     * @return     */    public static List getActivities(Context context, String packageName, List excludeActivities) {        final String TAG = "GET_ACTIVITY";        List includeActivities = new ArrayList<>();        try {            PackageInfo packageInfo = context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);            if (packageInfo.activities != null) {                ActivityInfo[] activityInfos = packageInfo.activities;                Log.d(TAG, "Find " + activityInfos.length + " activity in AndroidManifest.xml.");                for (ActivityInfo activityInfo : activityInfos) {                    Class activityClass;                    String activityName = activityInfo.name;                    try {                        activityClass = Class.forName(activityName);                        if (Activity.class.isAssignableFrom(activityClass)) {                            includeActivities.add(activityClass);                        }                    } catch (ClassNotFoundException e) {                        Log.d(TAG, "Class not found activity " + activityName + " in package " + packageName);                    }                }            }            Log.d(TAG, "Found  " + includeActivities.size() + " activity list is :" + Arrays.toString(includeActivities.toArray()));            if (null != excludeActivities) {                includeActivities.removeAll(excludeActivities);            }            Log.d(TAG, "Last  " + includeActivities.size() + " activity  list is :" + Arrays.toString(includeActivities.toArray()));        } catch (PackageManager.NameNotFoundException e) {            Log.d(TAG, "Android system not found package " + packageName);        }        return includeActivities;    }}

在AndroidManifest.xml中讲辅助Activity设置为默认启动的Activity，之后就可以通过选择点击要启动的Activity来进行测试。该示例还可以通过添加一些代码来增强，比如启动Activity的时候可以通过输入对话框的方式携带数据至启动的Activity。测试完成后删除或者充足默认启动的Activity即可。

2. 配置AndroidManifest.xml :

3. 调试日志：

11-15 20:07:31.899 10665-10665/secondriver.app D/GET_ACTIVITY: Find 3 activity in AndroidManifest.xml.11-15 20:07:31.899 10665-10665/secondriver.app D/GET_ACTIVITY: Found activity have 3 list is :[class secondriver.app.TestActivitiesActivity, class secondriver.app.OneActivity, class secondriver.app.TwoActivity]11-15 20:07:31.899 10665-10665/secondriver.app D/GET_ACTIVITY: Last activity have 2 list is :[class secondriver.app.OneActivity, class secondriver.app.TwoActivity]

从日志中可以看到一共发现了3个Activity类，去除辅助的Activity，在ListView中讲显示2个Item项。

后期追加内容：

新源码参见附件：TestActivitiesActivity.java.txt

Item状态变化Drawable文件内容如下：
