android activity自定义抽象父类

android开发最常用的组件就是activity，但是activity中也有很多常用的方法，几乎每次建立activity后都需要调用的一些方法流程，在此自定义一个父类-BaseActivity，使所有的activity都继承于这个父类，继承以后会自动继承父类的方法，并集成了一些界面跳转动画等公共效果，

BaseActivity.java

public abstract class BaseActivity extends AppCompatActivity {
protected Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView();
setContentView(R.layout.activity_base_layout);
initParent();
findViews();
setListensers();
MyApplication myApplication = (MyApplication) getApplication();
myApplication.addTempActivityInBackStack(this);
}

@Override
protected void onActivityResult(int arg0, int arg1, Intent arg2) {
// TODO Auto-generated method stub
super.onActivityResult(arg0, arg1, arg2);
}

private void initParent() {
mContext = this;
LinearLayout subCententView = (LinearLayout) this.findViewById(R.id.base_sub_activty_layout);
LayoutParams layoutParams = new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
View centerView = View.inflate(mContext, setContentView(), null);
subCententView.addView(centerView, layoutParams);
}

protected boolean isShowNoNetworksPrompt() {
return true;
}

/**
* 跳转到某个Activity
*/
protected void gotoActivity(Context mContext, Class<?> toActivityClass, Bundle bundle) {
Intent intent = new Intent(mContext, toActivityClass);
if (bundle != null) {
intent.putExtras(bundle);
}
mContext.startActivity(intent);
((Activity) mContext).overridePendingTransition(R.anim.push_right_in, R.anim.not_exit_push_left_out);//页面跳转动画
}

/**
* 退出到某个Activity
*/
protected void backActivity() {
finish();
overridePendingTransition(R.anim.not_exit_push_left_in, R.anim.push_right_out);//页面退出动画
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// 所有需要统一处理的onKeyDown写在这个if里面
if (isOnKeyDown()) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
backActivity();
}
}
return super.onKeyDown(keyCode, event);
}

protected boolean isOnKeyDown() {
return true;
}

/**
* 加载子类布局
*/
protected abstract int setContentView();

/**
* 加载控件
*/
protected abstract void findViews();

/**
* 设置监听
*/
protected abstract void setListensers();

@Override
protected void onResume() {
super.onResume();
MyApplication myApplication = (MyApplication) getApplication();
myApplication.setResumeContext(this);
if (JPushInterface.isPushStopped(getApplicationContext())) {
JPushInterface.resumePush(getApplicationContext());
}
}
}
