WorkFlow
简化顺序调用方法之间的嵌套和耦合:
-
轻松替换方法调用之间的顺序关系
-
提高代码简洁性和可读性、降低维护成本
- 增删改方便,提高效率
Installation:
dependencies {
implementation 'com.qw:workflow:0.0.2'
}
Usage:
场景示例1
依次顺序的展示Toast,Dialog,SnackBar:
private static final int STEP_TOAST = 1;
private static final int STEP_DIALOG = 2;
private static final int STEP_SNACK_BAR = 3;
private void startWorkFlow() {
new WorkFlow.Builder()
.withNode(WorkNode.build(STEP_TOAST, new Worker() {
@Override
public void doWork(final Node current) {
//do any work you want
Toast.makeText(MainActivity.this, "step for toast", Toast.LENGTH_SHORT).show();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
//call it when finish work
current.onCompleted();
}
}, 2000);
}
}))
.withNode(WorkNode.build(STEP_SNACK_BAR, new Worker() {
@Override
public void doWork(final Node current) {
Snackbar.make(findViewById(R.id.btn_after), "step for snack_bar", Snackbar.LENGTH_SHORT).show();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
current.onCompleted();
}
}, 2000);
}
}))
.withNode(WorkNode.build(STEP_DIALOG, new Worker() {
@Override
public void doWork(final Node current) {
new AlertDialog.Builder(MainActivity.this)
.setTitle("step for show dialog")
.setPositiveButton("complete", null)
.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialogInterface) {
current.onCompleted();
}
}).create().show();
}
})).create()
.start();
}
效果如图:
假如现在需要让Dialog和SnackBar,替换位置,只需要让Dialog定义值比SnackBar大即可:
private static final int STEP_TOAST = 1;
private static final int STEP_DIALOG = 20;
private static final int STEP_SNACK_BAR = 3;
效果如下:
场景示例2
进入APP首页按顺序请求3个接口,第一个接口和第三个接口成功后启动对话框,第二个接口跳转到Web页面
public class AfterActivity extends AppCompatActivity {
private static final int REQUEST_CODE_H5 = 1;
/**
* 初次广告弹框
*/
private static final int NODE_FIRST_AD = 10;
/**
* 初次进入h5页
*/
private static final int NODE_CHECK_H5 = 20;
/**
* 初次进入的注册协议
*/
private static final int NODE_REGISTER_AGREEMENT = 30;
private WorkFlow workFlow;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_compare);
((TextView) findViewById(R.id.tv_desc)).setText("使用后");
startWorkFlow();
}
private void startWorkFlow() {
workFlow = new WorkFlow.Builder()
.withNode(getFirstAdNode())
.withNode(getShowRegisterAgreementNode())
.withNode(getShowH5Node())
.create();
workFlow.start();
}
private WorkNode getFirstAdNode() {
return WorkNode.build(NODE_FIRST_AD, new Worker() {
@Override
public void doWork(final Node current) {
Utils.fakeRequest("http://www.api1.com", new HttpCallBack() {
@Override
public void onOk() {
new AlertDialog.Builder(AfterActivity.this)
.setTitle("这是一条有态度的广告")
.setPositiveButton("我看完了", null)
.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialogInterface) {
//仅仅只需关心自己是否完成,下一个节点会自动执行
current.onCompleted();
}
}).create().show();
}
@Override
public void onFailure() {
//仅仅只需关心自己是否完成,下一个节点会自动执行
current.onCompleted();
}
});
}
});
}
private WorkNode getShowRegisterAgreementNode() {
return WorkNode.build(NODE_REGISTER_AGREEMENT, new Worker() {
@Override
public void doWork(final Node current) {
Utils.fakeRequest("http://www.api2.com", new HttpCallBack() {
@Override
public void onOk() {
new AlertDialog.Builder(AfterActivity.this)
.setTitle("这是注册协议")
.setPositiveButton("我看完了", null)
.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialogInterface) {
current.onCompleted();
}
}).create().show();
}
@Override
public void onFailure() {
current.onCompleted();
}
});
}
});
}
private WorkNode getShowH5Node() {
return (WorkNode.build(NODE_CHECK_H5, new Worker() {
@Override
public void doWork(final Node current) {
Utils.fakeRequest("http://www.api3.com", new HttpCallBack() {
@Override
public void onOk() {
startActivityForResult(new Intent(AfterActivity.this, TestH5Activity.class), REQUEST_CODE_H5);
}
@Override
public void onFailure() {
current.onCompleted();
}
});
}
}));
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CODE_H5:
workFlow.continueWork();
break;
default:
break;
}
}
}
效果:
流程:
功能介绍:
-
每个节点只关注自己是否完成:
private WorkNode getFirstAdNode() { return WorkNode.build(NODE_FIRST_AD, new Worker() { @Override public void doWork(final Node current) { //仅仅只需关心自己是否完成,下一个节点会自动执行 current.onCompleted(); } }); }
-
可以操作WorkFlow对象来控制全局节点
public class WorkFlow { /** * 标记为处理完成,调用后不再能执行任何开启的操作 */ public void dispose() /** * 给workflow添加一个工作节点 * * @param workNode 节点 */ public void addNode(WorkNode workNode) /** * 开始工作,默认从第一个节点 */ public void start() /** * 基于某个节点Id 开始工作 * * @param startNodeId 节点id */ public void startWithNode(int startNodeId) /** * 让当前工作流继续工作 * 效果等同于当前节点调用 Node.onCompleted */ public void continueWork() /** * 回退 * 基于最近节点回退至上一节点 */ public void revert() }
