单击 View Holder 时出现 ActivityNotFoundException 错误

Question

我正在解决一个 Simple todo 应用程序的代码路径准备工作问题。我创建了一个侦听器，这样当单击 Adapter Holder 时，它将打开另一个编辑 activity，可以在其中编辑项目，但问题是它显示 ActivityNotFoundException 错误

这是部分清单文件


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.SimpleToDo"
        tools:ignore="ExtraText">
        <activity android:name=".EditActivity" >
            <intent-filter>
                    <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

单击侦听器


 ItemsAdapter.OnClickListener onClickListener = new ItemsAdapter.OnClickListener() {
            @Override
            public void onItemClicked(int position) {
                Log.d("MainActivity","Single Click poistion :  " + position);
                // Create new activity
                Intent intent = new Intent(MainActivity.this, EditText.class);
                // pass the data being edited
                intent.putExtra(KEY_ITEM_TEXT, items.get(position));                
                intent.putExtra(KEY_ITEM_POSITION, position);
                // display the activity
                try {
                    /* your code */
                    startActivity(intent);
                } catch ( ActivityNotFoundException e) {
                    e.printStackTrace();
                }

            }
        };

Answer 1

您正在尝试前往 EditText 而不是 EditActivity

替换

Intent intent = new Intent(MainActivity.this, EditText.class);

与

Intent intent = new Intent(MainActivity.this, EditActivity.class);

Answer 2

您的 Activity 名称是“EditActivity”，但您正在为“EditText”创建 Intent。
