我正面对java.lang.IllegalStateException Required view 'splash_text'
,但我已将其包含在xml中。
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");
记录:
Caused by: java.lang.IllegalStateException: Required view 'splash_text' with ID 2131492944 for field 'mSplashTv' was not found. If this view is optional add '@Nullable' annotation.

更新
BaseActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ButterKnife.bind(this);
}
使用支持库:
compile 'com.android.support:appcompat-v7:23.1.1'

从基础活动中删除绑定。当ButterKnife在基类中绑定时,你的布局还没有膨胀 您还可以将 @Nullable 注释添加到字段中。
答案 1 :(得分:2)
这是因为您的布局尚未膨胀。如果您使用 BaseActivity ,请执行以下操作:
public abstract class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(this.getLayoutContentViewID());
ButterKnife.bind(this); //Configure Butterknife
}
public abstract int getLayoutContentViewID();
}
接下来,在 MainActivity :
中public class MainActivity extends BaseActivity {
@BindView(R.id.main_activity_coordinator_layout) CoordinatorLayout coordinatorLayout;
...
@Override
public int getLayoutContentViewID() { return R.layout.activity_main; }
...
}

检查您的支持库版本。自从我将支持库升级到23版本后,我收到了上述错误。可能是导致错误。NavigationView get/find header layout
