单独修改和编译Camera2

先找到包名

maqi@ubuntu:~/data/android-11.0.0_r9$ adb shell dumpsys window | grep  mCurrentFocusmCurrentFocus=Window{dc54f28 u0 com.android.camera2/com.android.camera.CameraLauncher}

targetActivity 找到 CameraActivity

  <activity-aliasandroid:name="com.android.camera.CameraLauncher"android:label="@string/app_name"android:targetActivity="com.android.camera.CameraActivity"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.DEFAULT" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity-alias>

加入一个标志

<com.android.camera.ui.MainActivityLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/activity_root_view"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@null"><include layout="@layout/camera" /><include layout="@layout/camera_filmstrip" /><com.android.camera.ui.ModeTransitionViewandroid:id="@+id/mode_transition_view"android:visibility="gone"android:layout_width="match_parent"android:layout_height="match_parent" /><TextViewandroid:id="@+id/txtOne"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="MAQI666"android:textColor="#EA5246"android:textStyle="bold|italic"android:background="#000000"android:textSize="18sp" /></com.android.camera.ui.MainActivityLayout>
