多个入口进入MainActivity.java中，需要在清单文件中定义activity-alias属性；

【Android|Android app的多个快捷方式】Activity中的代码：

public class MainActivity extends Activity {private final String ACTIVITY_ALIAS_1 = "com.example.dynamicchangeicon.ActivityAlias1"; private final String ACTIVITY_ALIAS_2 = "com.example.dynamicchangeicon.TestAlias"; private SharedPreferences preferences; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); preferences = getSharedPreferences("DynamicChangeIcon", Context.MODE_PRIVATE); preferences.edit().putInt("ikey", 1).commit(); }private void changeIcon(String msg) { //msg 就是在清单文件给activity-alias定制的name属性： // android:name="com.example.dynamicchangeicon.ActivityAlias1"PackageManager pm = getApplicationContext().getPackageManager(); ActivityManager am = (ActivityManager) getSystemService(Activity.ACTIVITY_SERVICE); System.out.println(getComponentName()); // 去除旧图标，不去除的话会出现2个App图标 pm.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); if(msg.equals(ACTIVITY_ALIAS_1)){ // 显示新图标 pm.setComponentEnabledSetting(new ComponentName(getBaseContext(), ACTIVITY_ALIAS_1), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); pm.setComponentEnabledSetting(new ComponentName(getBaseContext(), ACTIVITY_ALIAS_2), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); }else{ pm.setComponentEnabledSetting(new ComponentName(getBaseContext(), ACTIVITY_ALIAS_2), PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); pm.setComponentEnabledSetting(new ComponentName(getBaseContext(), ACTIVITY_ALIAS_1), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); }Intent i = new Intent(Intent.ACTION_MAIN); i.addCategory(Intent.CATEGORY_HOME); i.addCategory(Intent.CATEGORY_DEFAULT); List resolves = pm.queryIntentActivities(i, 0); for (ResolveInfo res : resolves) { if (res.activityInfo != null) { am.killBackgroundProcesses(res.activityInfo.packageName); } } }public void changeIcon(View v) { int key = preferences.getInt("ikey", 0); switch (key) { case 1: changeIcon(ACTIVITY_ALIAS_1); preferences.edit().putInt("ikey", 2).commit(); break; case 2: changeIcon(ACTIVITY_ALIAS_2); preferences.edit().putInt("ikey", 1).commit(); break; }} }
