#录屏

本文介绍了Android桌面悬浮窗的录屏功能，包括RecordScreenController接口及其实现RecordScreenControllerImpl，以及在system UI中展示图标的RecordScreenTitle。源码适用于系统UI，若要应用于其他应用，需要进行相应修改。

1.录屏控制类接口封装RecordScreenController.java

package com.android.systemui.statusbar.policy;

import com.android.systemui.Dumpable;
import com.android.systemui.statusbar.policy.RecordScreenController.RecordScreenListener;

public interface RecordScreenController extends CallbackController<RecordScreenListener> {

    void setRecordScreen(boolean newState);
    boolean isEnabled();
    void setRecordScreenController(boolean enabled);
    boolean getRecordScreenController();
    void addCallback(RecordScreenListener callback);
    void removeCallback(RecordScreenListener callback);
    boolean isAvailable();


    public interface RecordScreenListener {

        /**
         * Called when the flashlight was turned off or on.
         * @param enabled true if the flashlight is currently turned on.
         */
        void onRecordScreenChanged(boolean enabled);

2.录屏控制了具体控制实现RecordScreenControllerImpl.java

package com.android.systemui.statusbar.policy;

import android.content.Context;
import android.os.UserHandle;
import android.content.Intent;
import com.android.internal.view.RotationPolicy;

import java.util.concurrent.CopyOnWriteArrayList;
import com.android.systemui.statusbar.policy.RecordScreenController;
import com.android.systemui.statusbar.policy.RecordScreenController.RecordScreenListener;
import android.util.Log;
import com.android.systemui.util.ScreenUtil;
import android.app.Application;
import com.android.systemui.ScreenRecordActivity;

/** Platform implementation of the rotation lock controller. **/
public final class RecordScreenControllerImpl implements RecordScreenController {
    private final String TAG = "RecordScreenControllerImpl";
