在项目开发时如果app大部分界面的风格类似以及界面转场动画相同，
例如统一样式的titlebar和bottomBar，沉浸样式，中间部分是内容，处理网络异常和没有数据时的显示样式风格相同，那么可以将不变的部分封装到某个activity中，通过继承去现实不同数据
在基础activity中实现沉浸样式
public class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setupTransparencyStatus();
ATStatusBarUtils.StatusBarLightMode(this);
}

window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS

window.getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

}
}

实现沉浸式后通过继承BaseActivity实现界面动画
public class ATTranslucentActivity extends BaseActivity {
private ATSwipeBackLayout ATSwipeBackLayout = null;
private boolean needAnimation = true;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public void setContentView(int layoutResID) {
super.setContentView(layoutResID);
initSlideBack();
}
@Override
public void setContentView(View view) {
super.setContentView(view);
initSlideBack();
}
protected void onResume() {
super.onResume();
ATSwipeBackLayout.dealWithNightMode();
}
@Override
protected void onPause() {
super.onPause();
if (needAnimation) {
ATActivityAnimation.leftOut(this);
}
}
public void setNeedAnimation(boolean b) {
needAnimation = b;
}
@Override
public void startActivity(Intent intent) {
super.startActivity(intent);
if (needAnimation) {
ATActivityAnimation.rightIn(this);
}
}
/**
* set sliding mode
*
* @param mode
*/
public void setSlidingMode(ATSwipeBackLayout.Sliding mode) {
if (ATSwipeBackLayout == null) {
throw new NullPointerException("ATSwipeBackLayout is null,Please call after the setContentView");
}
ATSwipeBackLayout.setSlidingMode(mode);
}
@Override
public void startActivityForResult(Intent intent, int requestCode) {
super.startActivityForResult(intent, requestCode);
if (needAnimation) {
ATActivityAnimation.rightIn(this);
}
}
@SuppressLint("InflateParams")
private void initSlideBack() {
ATSwipeBackLayout = (ATSwipeBackLayout) LayoutInflater.from(this).inflate(R.layout.swipeback_layout, null);
ATSwipeBackLayout.attachToActivity(this);
}
protected void setEnableGesture(boolean b) {
ATSwipeBackLayout.setEnableGesture(b);
}
}再通过继承转场动画activity的实现界面风格统一，例如统一的titleBar和bottomBar和数据为null或者网络异常时的处理
public abstract class ATTitleActivity extends ATTranslucentActivity {
View mTitleView;
View failedView;
View content;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.at_titile_bar);
}
@Override
protected void onResume() {
super.onResume();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
private void initView() {
}
//网络加载失败后重新请求网络
public void clickToRetry(ATErrorPage atErrorPage) {
}
public void showNoNetWork() {
container.setVisibility(View.GONE);
failedView.setVisibility(View.VISIBLE);
failedImage.setImageResource(R.drawable.failed_wifi_icon);
failedFirstText.setText(ATResUtil.getStringById(R.string.at_no_network));
failedSecondText.setVisibility(View.GONE);
clickHint.setText(ATResUtil.getStringById(R.string.at_click_wifi_load));
this.atErrorPage = ATErrorPage.WIFI_ERROR;
}
public void showNoData() {
container.setVisibility(View.GONE);
failedView.setVisibility(View.VISIBLE);
failedImage.setImageResource(R.drawable.failed_no_data_icon);
failedFirstText.setText(ATResUtil.getStringById(R.string.at_no_failed_data));
failedSecondText.setVisibility(View.GONE);
clickHint.setText(ATResUtil.getStringById(R.string.at_click_no_data_load));
this.atErrorPage = ATErrorPage.EMPTY_ERROR;
}
public void showServerError(String message) {
container.setVisibility(View.GONE);
failedView.setVisibility(View.VISIBLE);
failedImage.setImageResource(R.drawable.failed_server_icon);
failedFirstText.setText(ATStringUtil.isEmpty(message) ? (ATResUtil.getStringById(R.string.at_server_error_first_text)) : message);
failedSecondText.setText(ATResUtil.getStringById(R.string.at_server_error_second_text));
clickHint.setText(ATResUtil.getStringById(R.string.at_click_wifi_load));
this.atErrorPage = ATErrorPage.SERVER_ERROR;
}
public void showContentView() {
container.setVisibility(View.VISIBLE);
failedView.setVisibility(View.GONE);
this.atErrorPage = ATErrorPage.NONE;
}
//子类只在content区域编写界面 @Override
public void setContentView(int layoutResID) {
View view = getLayoutInflater().inflate(layoutResID, null);
/* if (container == null) {
finish();
Intent it = new Intent();
it.setClass(this, SplashActivity.class);
it.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(it);
return;
}*/
container.addView(view, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
}
@Override
protected void onDestroy() {
super.onDestroy();
}
public void setTitle(CharSequence title) {
titleText.setText(title);
}
public void setTitle(int resouceId) {
titleText.setText(resouceId);
}
@SuppressLint("NewApi")
public void onSetTitleVisible() {
mTitleView.setVisibility(View.VISIBLE);
}
@SuppressLint("NewApi")
public void onSetTitleGone() {
mTitleView.setVisibility(View.GONE);
iv_divider.setVisibility(View.GONE);
}
public ViewGroup getTitleView() {
return mTitleView;
}
}到此大体介绍完毕，在沉浸式式默认是没有显示状态栏的，为了显示状态栏需要在
at_titile_bar布局文件中加入android:fitsSystemWindows="true"即可
