State switching, so that the View state switch and Activity completely separate. Using builder mode to freely add the required state View, can set data, data is empty, load data error, network error, load and other states, and support the layout of custom state. At present has been used in other formal projects, strong expansion!

YCStateLayout State Switching

0.Dependency

0.1 Used

  • Add this in your root build.gradle file (not your module build.gradle file):
    allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }
    
  • Then, add the library to your module build.gradle
    implementation  'cn.yc:YCStateLib:1.1.6'
    

0.2 Basic introduction

Function introduction
  • State switching, so that the View state switch and Activity completely separate. Using builder mode to freely add the required state View, can set data, data is empty, load data error, network error, load and other states, and support the layout of custom state. At present has been used in other formal projects, strong expansion!

1.An introduction to the switching State of Android Interface

1.1 Problems encountered in development

  • How to switch the interface state?
  • Some interfaces want to customize custom state?
  • How does the state add a click event?

1.2 You can set up more than 5 state View

  • content interface view
  • loading data view
  • loading data error view
  • no data after loading view
  • no network view

2.Train of thought change, extract separate class management several kinds of state

2.1 Previous practice:

  • Directly include these interfaces into the main interface, then dynamically switch the interface, later found that this processing is not easy to reuse in other projects, and in activity to deal with the display and hiding of these states is messy
  • Using the child class to inherit the parent property, write the switching state in the parent class, but what can some interfaces do if they do not inherit the parent class

2.2 Present practice:

  • The switching of View states is completely separated from Activity. The View of these states must be encapsulated in a management class and several methods are exposed to implement the switching between View.
  • The View that can be required varies from project to project, so consider designing the management class as an builder schema to freely add the required state View

3.An Analysis of the advantages of this State switching tool

  • Free to switch content, empty data, exception error, load, network error, etc.
  • The parent class BaseActivity directly exposes the state in 5, making it easy for subclasses to uniformly manage state switching
  • If some pages want to customize the state layout, they can also be implemented freely, simple

4.usage method

4.1 Specific use

  • As shown below, you can refer directly to the code, and more directly see the demo
    statusLayoutManager = StateLayoutManager.newBuilder(this)
                .contentView(R.layout.activity_content)
                .emptyDataView(R.layout.activity_emptydata)
                .errorView(R.layout.activity_error)
                .loadingView(R.layout.activity_loading)
                .netWorkErrorView(R.layout.activity_networkerror)
                .build();
    
    
    /**
     * Click to refresh the data
     */
    private void initEmptyDataView() {
        statusLayoutManager.showEmptyData();
        LinearLayout ll_empty_data = (LinearLayout) findViewById(R.id.ll_empty_data);
        ll_empty_data.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                initData();
                adapter.notifyDataSetChanged();
                showContent();
            }
        });
    }
    
    /**
     * Click to refresh
     */
    private void initErrorDataView() {
        statusLayoutManager.showError();
        LinearLayout ll_error_data = (LinearLayout) findViewById(R.id.ll_error_data);
        ll_error_data.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                initData();
                adapter.notifyDataSetChanged();
                showContent();
            }
        });Click to refresh
    }
    
    /**
     * Click set up the network
     */
    private void initSettingNetwork() {
        statusLayoutManager.showNetWorkError();
        LinearLayout ll_set_network = (LinearLayout) findViewById(R.id.ll_set_network);
        ll_set_network.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent("android.settings.WIRELESS_SETTINGS");
                startActivity(intent);
            }
        });
    }
