Android内部线程集中管理，不能直接new Handler new WebView?

把更多的公用性的东西写成可配置化的？
> Android BaseActivity封装
1.BaseParentActivity抽象类封装
public abstract class BaseParentActivity extends RxAppCompatActivity implements BaseViewInterface { protected LayoutInflater mInflater; protected Context mContext; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); AppManager.getAppManager().addActivity(this); if (getLayoutId() != 0) { setContentView(getLayoutId()); } mInflater = getLayoutInflater(); mContext = this; initTitleBar(); initView(); initData(); } /** * 打开一个Activity 默认 不关闭当前activity * @param clz */ public void gotoActivity(Class<?> clz) { gotoActivity(clz, false, null); } public void gotoActivity(Class<?> clz,boolean isCloseCurrentActivity) { gotoActivity(clz, isCloseCurrentActivity, null); } public void gotoActivity(Class<?> clz,boolean isCloseCurrentActivity,Bundle ex) { Intent intent=new Intent(this, clz); if(ex!=null) intent.putExtras(ex); startActivity(intent); if (isCloseCurrentActivity) { finish(); } } @Override protected void onDestroy() { super.onDestroy(); } protected int getLayoutId() { return 0; } protected void initTitleBar() { } } 2. BaseActivity抽象类进一步封装 public abstract class BaseActivity extends BaseParentActivity implements View.OnClickListener{ @BindView(R.id.title_text) protected TextView mTitleText; @BindView(R.id.back_img) protected ImageView mBackBtn; @BindView(R.id.right_img) protected ImageView mRightBtn; @Override protected void initTitleBar() { ButterKnife.bind(this); } @Override @OnClick({R.id.back_img}) public void onClick(View view) { switch (view.getId()) { case R.id.back_img: onBackPressed(); break; default: break; } } } 3. CommentActivity实现 public class CommentActivity extends BaseActivity { @Override protected int getLayoutId() { return R.layout.activity_comment; } @Override public void initView() { mTitleText.setText(R.string.comment); } @Override public void initData() { } }
-- WebView单例封装 Android ? -- 全局Handler的封装- https://blog.csdn.net/Crazyencode/article/details/79997907 public class GlobalHandler extends Handler{ private HandleMsgListener listener; private String Tag = GlobalHandler.class.getSimpleName(); //使用单例模式创建GlobalHandler private GlobalHandler(){ Log.e(Tag,"GlobalHandler创建"); } private static class Holder{ private static final GlobalHandler HANDLER = new GlobalHandler(); } public static GlobalHandler getInstance(){ return Holder.HANDLER; } @Override public void handleMessage(Message msg) { super.handleMessage(msg); if (getHandleMsgListener() != null){ getHandleMsgListener().handleMsg(msg); }else { Log.e(Tag,"请传入HandleMsgListener对象"); } } public interface HandleMsgListener{ void handleMsg(Message msg); } public void setHandleMsgListener(HandleMsgListener listener){ this.listener = listener; } public HandleMsgListener getHandleMsgListener(){ return listener; } }
public class MainActivity extends AppCompatActivity implements GlobalHandler.HandleMsgListener{ private GlobalHandler mHandler; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mHandler = GlobalHandler.getInstance(); mHandler.setHandleMsgListener(this); mHandler.sendEmptyMessage(0); mHandler.sendEmptyMessage(1); } @Override public void handleMsg(Message msg) { switch (msg.what){ case 0: Toast.makeText(MainActivity.this,"test0",Toast.LENGTH_SHORT).show(); break; case 1: Toast.makeText(MainActivity.this,"test1",Toast.LENGTH_SHORT).show(); break; } } @Override protected void onDestroy() { super.onDestroy(); //销毁移除所有消息，避免内存泄露 mHandler.removeCallbacks(null); } }
