Question

我有EditText()：

<EditText
            android:id="@+id/СA_EtFirN"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:hint="@string/CA_EtFirN"
            android:textColor="@color/SSA_TvColor"
            android:textStyle="italic"
            android:layout_gravity="center"
            android:gravity="center_horizontal"/>

所以当你看到android:id="@+id/СA_EtFirN"时。然后我有一个Activity.java，我想定义我的EditText()：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.contacts);

    Log.i(TAG, "Start definition");
    tv1 = (TextView) findViewById(R.id.CA_Tv1);
    et1 = (EditText) findViewById(R.id.CA_EtFirN);
}

但是CA_EtFirN标有红色下划线。所以我的程序没有看到它。有什么想法吗？

我的R.id

P.S使用TextView即可。

Answer 1

尝试将layout.xml中的id复制/粘贴到代码中（反之亦然），以确保您没有在名称中混合使用西里尔字符和拉丁字符。

Answer 2

尝试清理项目并重建，有时候R.java没有很好地更新。

Answer 3

这很奇怪））如果我复制CA_EtFirN就可以了。但是，如果我写了id的名字（同名，我已经检查!!!）这是一个错误）

Answer 4

在java类中检查import语句android.R 如果存在则删除该导入语句，然后清理项目，然后再次运行并对结果进行评论

findViewById看不到我的EditText的id
