问题描述
我正在面对java.lang.IllegalStateException Required view 'splash_text'

I am facing java.lang.IllegalStateException Required view 'splash_text'
but I have included it in the xml.
我正在使用Butterknife
绑定视图.
compile 'com.jakewharton:butterknife:7.0.1'
Xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_orange_light">
<com.CustomTextView
android:id="@+id/splash_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
活动:
@Bind(R.id.splash_text)
CustomTextView mSplashTv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
ButterKnife.bind(this);
mSplashTv.setText("Splash");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
finishSplash();
}
},3000);
}
应用程序在mSplashTv.setText("Splash");

更新:
BaseActivity:
BaseActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ButterKnife.bind(this);
}
使用的支持库:
compile 'com.android.support:appcompat-v7:23.1.1'
推荐答案
从基本活动中删除绑定.当ButterKnife在基类中绑定时,您的布局尚未膨胀.
您也可以在字段中添加 @Nullable 注释.
Remove binding from base activity. When ButterKnife bind in base class, your layout not inflated yet.
Also you can add @Nullable annotation to field.
