一、xml布局
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:id="@+id/coordinatorLayout"android:layout_width="@dimen/dp_640"android:layout_height="@dimen/dp_400"android:background="@color/pageBgColor"android:orientation="vertical"><!-- 视频预览 --><csu.xiaoya.robotApp.ui.activity.homepage.familydct.bean.DraggableTextureViewandroid:id="@+id/preview"android:layout_width="@dimen/dp_640"android:layout_height="@dimen/dp_400"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintLeft_toRightOf="parent"app:layout_constraintTop_toTopOf="parent" /><!-- 远程视频 --><csu.xiaoya.robotApp.ui.activity.homepage.familydct.bean.DraggableTextureViewandroid:id="@+id/remoteUserView"android:layout_width="150dp"android:layout_height="180dp"android:layout_marginTop="30dp"android:layout_marginRight="30dp"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintLeft_toRightOf="parent"app:layout_constraintTop_toTopOf="parent" /><ImageViewandroid:id="@+id/imHead"android:layout_width="@dimen/dp_120"android:layout_height="@dimen/dp_120"android:layout_gravity="center"android:layout_marginBottom="@dimen/dp_100"android:scaleType="centerCrop"android:src="@mipmap/doctor_head"app:layout_constraintBottom_toBottomOf="parent"app:layout_constraintEnd_toEndOf="parent"app:layout_constraintStart_toStartOf="parent"app:layout_constraintTop_toTopOf="parent" /><ImageViewandroid:id="@+id/changeVideoWindows"android:layout_width="@dimen/dp_30"android:layout_height="@dimen/dp_30"android:layout_marginLeft="@dimen/dp_30"android:layout_marginTop="@dimen/dp_30"android:background="@drawable/change_windows"android:src="@mipmap/video_windows_change"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
二、切换代码
/*** 通话大小* 窗口切换*/private boolean isLocalVideoSmallState = true;private void switchWindowMode(VideoChatDialog videoChatDialog, boolean isLocalVideoSmall) {ConstraintLayout constraintLayout = videoChatDialog.findViewById(R.id.coordinatorLayout);TextureView localVideoTextureView = videoChatDialog.findViewById(R.id.preview);TextureView remoteVideoTextureView = videoChatDialog.findViewById(R.id.remoteUserView);ImageView changeVideoWindows = videoChatDialog.findViewById(R.id.changeVideoWindows);ConstraintSet constraintSet = new ConstraintSet();constraintSet.clone(constraintLayout);if (isLocalVideoSmall) {constraintLayout.removeView(localVideoTextureView);constraintLayout.removeView(remoteVideoTextureView);constraintLayout.removeView(changeVideoWindows);constraintLayout.addView(remoteVideoTextureView);constraintLayout.addView(localVideoTextureView);constraintLayout.addView(changeVideoWindows);// 远程端全屏模式remoteVideoTextureView.setEnabled(false);constraintSet.clear(remoteVideoTextureView.getId());constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP, 0);constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.END, ConstraintSet.PARENT_ID, ConstraintSet.END, 0);constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.RIGHT, ConstraintSet.PARENT_ID, ConstraintSet.RIGHT, 0);constraintSet.constrainWidth(remoteVideoTextureView.getId(), 1280);constraintSet.constrainHeight(remoteVideoTextureView.getId(), 800);// 本地小窗口localVideoTextureView.setEnabled(true);constraintSet.clear(localVideoTextureView.getId());constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP, 30);constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.END, ConstraintSet.PARENT_ID, ConstraintSet.END, 0);constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.RIGHT, ConstraintSet.PARENT_ID, ConstraintSet.RIGHT, 30);constraintSet.constrainWidth(localVideoTextureView.getId(), 300); // 设置小窗口的宽度constraintSet.constrainHeight(localVideoTextureView.getId(), 200);isLocalVideoSmallState = false;} else {constraintLayout.removeView(remoteVideoTextureView);constraintLayout.removeView(localVideoTextureView);constraintLayout.removeView(changeVideoWindows);constraintLayout.addView(localVideoTextureView);constraintLayout.addView(remoteVideoTextureView);constraintLayout.addView(changeVideoWindows);// 本地 全屏模式localVideoTextureView.setEnabled(false);constraintSet.clear(localVideoTextureView.getId());constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP, 0);constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.END, ConstraintSet.PARENT_ID, ConstraintSet.END, 0);constraintSet.connect(localVideoTextureView.getId(), ConstraintSet.RIGHT, ConstraintSet.PARENT_ID, ConstraintSet.RIGHT, 0);constraintSet.constrainWidth(localVideoTextureView.getId(), 1280);constraintSet.constrainHeight(localVideoTextureView.getId(), 800);// 远程 小窗口remoteVideoTextureView.setEnabled(true);constraintSet.clear(remoteVideoTextureView.getId());constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP, 30);constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.END, ConstraintSet.PARENT_ID, ConstraintSet.END, 0);constraintSet.connect(remoteVideoTextureView.getId(), ConstraintSet.RIGHT, ConstraintSet.PARENT_ID, ConstraintSet.RIGHT, 30);constraintSet.constrainWidth(remoteVideoTextureView.getId(), 300); // 设置小窗口的宽度constraintSet.constrainHeight(remoteVideoTextureView.getId(), 200);isLocalVideoSmallState = true;}constraintSet.applyTo(constraintLayout);}
三、自定义可拖拽TextureView
/*** 自定义可拖动* TextureView*/public class DraggableTextureView extends TextureView {private float lastX;private float lastY;private boolean isDragging;public DraggableTextureView(Context context) {super(context);init();}public DraggableTextureView(Context context, @Nullable AttributeSet attrs) {super(context, attrs);init();}public DraggableTextureView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);init();}private void init() {setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {switch (event.getAction()) {case MotionEvent.ACTION_DOWN:lastX = event.getRawX();lastY = event.getRawY();isDragging = true;break;case MotionEvent.ACTION_MOVE:if (isDragging) {float dx = event.getRawX() - lastX;float dy = event.getRawY() - lastY;int newLeft = (int) (v.getLeft() + dx);int newTop = (int) (v.getTop() + dy);int newRight = (int) (v.getRight() + dx);int newBottom = (int) (v.getBottom() + dy);v.layout(newLeft, newTop, newRight, newBottom);lastX = event.getRawX();lastY = event.getRawY();}break;case MotionEvent.ACTION_UP:case MotionEvent.ACTION_CANCEL:isDragging = false;break;}return true;}});}}
