TransparentFragment

use a transparent fragment to handle callbacks of activity in listener style api

202509 新api

• 基于ActivityResultLauncher+透明activity
• 静态方法,统一回调,任何地方都可以调用,无需在oncreate里
• 回调时机为透明activity destory后,回调里再获取top activity 为真实可用的activity.

implementation 'com.github.hss01248.StartActivityResult:activityresult2:2.0.1'

api

​ //有真实result的:

// 准备目标Intent
        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_PICK);

        StartActivityResultHelper.startForResult(this, intent, new ActivityResultCallback() {
            @Override
            public void onActivityResult(int resultCode, @Nullable Intent data) {
                LogUtils.w(resultCode,data);
            }

            @Override
            public void onActivityNotFound(Throwable e) {

            }
        });

//没有真实result的:

			Intent intent = new Intent();
        // 设置动作：打开应用详情页面
        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        // 设置要打开的应用的包名（这里使用当前应用的包名）
        Uri uri = Uri.fromParts("package", getPackageName(), null);
        intent.setData(uri);
        StartActivityResultHelper.startForResult(this, intent, new ActivityResultCallback() {
            @Override
            public void onActivityResult(int resultCode, @Nullable Intent data) {
                LogUtils.w(resultCode,data);
              //resultCode统一为cancel,权限开关等场景自行判断权限有无
            }

            @Override
            public void onActivityNotFound(Throwable e) {

            }
        });

下面为老的api:

gradle

Add the JitPack repository in your build.gradle (top level module):

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

And add next dependencies in the build.gradle of the module:

dependencies {
   implementation 'com.github.hss01248.StartActivityResult:activityresult:1.0.1'//依赖这一个即可
   implementation   'com.github.hss01248.StartActivityResult:transfrag:1.0.1'
   
   com.github.hss01248.StartActivityResult:activityresult:1.1.2
com.github.hss01248.StartActivityResult:transactivity:1.1.2 //使用dialog样式的activity
com.github.hss01248.StartActivityResult:transfrag:1.1.2
   
}

BaseTransFragment

define a class extends BaseTransFragment

define your own api in the fragment,and use it

just like:

new GoOutOfAppForResultFragment(fragment,info).goOutApp(listener);

基于透明fragment的长流程封装技巧

startActivity and getResult

start a activity and set data in it's onCreate listener, rather then send data by parcelable

and get result in listener, not in activity's onActivityResult callback

接口定义:

public interface ActivityResultListener {

    /**
     *
     * @param fragment
     * @param intent
     * @return 返回值代表是否拦截原默认行为. 如果
     * 调用处为: if(!listener.onInterceptStartIntent(this,bean)){
     *                 startActivityForResult(bean,requestCode);
     *             }
     */
    default boolean onInterceptStartIntent(@NonNull Fragment fragment, @Nullable Intent intent, int requestCode){
        return false;
    }

    /**
     * 在里面自己处理
     * @param requestCode
     * @param resultCode
     * @param data
     */
     void onActivityResult(int requestCode, int resultCode, @Nullable Intent data);





     void onActivityNotFound(Throwable e) ;
}

StartActivityUtil.startActivity(this, ActivityDemo2.class, null,true,
        new TheActivityListener<ActivityDemo2>() {
            @Override
            public void onActivityCreated(@NonNull ActivityDemo2 activity, @Nullable Bundle savedInstanceState) {
            //这里设置数据,然后在具体activityOnCreate()方法的super.onCreate()之后直接拿数据
                activity.setData(666);
                Toast.makeText(activity, "activity oncreate 回调", Toast.LENGTH_LONG).show();
            }

            @Override
            protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
                super.onActivityResult(requestCode, resultCode, data);
                Toast.makeText(MainActivity.this, "activity onActivityResult 回调", Toast.LENGTH_LONG).show();
            }
        });

start a intent to open a third party app and recheck result in callback:

StartActivityUtil.goOutAppForResult(this, intent, new OutActivityResultListener() {


    @Override
    public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        boolean hasPermission =   NotificationManagerCompat.from(MainActivity.this).areNotificationsEnabled();
        Toast.makeText(MainActivity.this,"通知栏权限:"+hasPermission,Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onActivityNotFound(Throwable e) {

    }
});
