调用finish()并重新启动应用程序后的木材重复日志 [英] Timber duplicate logs after calling finish() and restarting app

问题描述

我的TextView上有一个 onTouchListener .触摸时，我用Timber.i()登录，然后呼叫finish().如果在finish()之后，我再次启动我的应用程序，然后再次单击TextView，它将记录两次，然后记录3次，等等...

I have an onTouchListener on my TextView. On touch, I log with Timber.i() and then I call finish(). If after finish(), I launch my app again, and click again on the TextView, It will log twice, then 3 times, etc...

(如果我将Timber.i()替换为普通的Log.i()，就没有问题)

(If I replace Timber.i() by the normal Log.i(), there is no problem)

// first time
Clicked

// second time
Clicked
Clicked

// etc...
Clicked
Clicked
Clicked

木材版本:

compile 'com.jakewharton.timber:timber:4.5.1'

工作代码:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Timber.plant(new Timber.DebugTree());

    TextView tv = (TextView) findViewById(R.id.mytextview);
    tv.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Timber.i("Clicked");
            finish();
            return false;
        }
    });
}

布局:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.caca.test.MainActivity">

    <TextView
        android:id="@+id/mytextview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

</android.support.constraint.ConstraintLayout>

推荐答案

问题是您正在活动"(c2)方法中植树".相反，请使用自定义的Applications子类并在其中种植树.

The problem is that you are 'planting' trees in the Activities onCreate method. Instead, use a custom Applications subclass and plant the trees there.

class MyApp : Application() {

    override fun onCreate() {
        super.onCreate()

        if (BuildConfig.DEBUG) {
             Timber.plant(DebugTree())
        }
    }
}

并相应地更新您的AndroidManifest:

And update your AndroidManifest accordingly:

<application android:name="com.foo.MyApp" android:icon="@mipmap/ic_launcher" android:label="@string/app_name"/>

<application android:name="com.foo.MyApp" android:icon="@mipmap/ic_launcher" android:label="@string/app_name"/>
