Android实现悬浮窗效果
作者:qq_21467035
这篇文章主要为大家详细介绍了Android实现悬浮窗效果,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了Android实现悬浮窗效果的具体代码,供大家参考,具体内容如下
一、权限:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
二、悬浮窗其实就是 WindowManager.addView(view,layoutParams),直接上代码
1、单例创建FloatWindowManager
/** 悬浮Manager */ public class FloatWindowManager { private volatile static FloatWindowManager mInstance; private WindowManager mWindowManager; private Context mContext; private WindowManager.LayoutParams mLayoutParams; private int layoutY; private int layoutX; private ValueAnimator animator; private TextView textView; public static synchronized FloatWindowManager getInstance() { if (mInstance == null) { synchronized (FloatWindowManager.class) { if (mInstance == null) { mInstance = new FloatWindowManager(); } } } return mInstance; } public FloatWindowManager initManager(Context context) { mContext = context; mWindowManager = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE); showWindow(); return this; } /** * 是否有悬浮框权限 * * @return */ public boolean requestPermission(Context context) { return SettingsCompat.canDrawOverlays(context, true, false); } /** * 加载 悬浮窗 没有内容 */ private synchronized void showWindow() { textView = new TextView(mContext); textView.setText("此为悬浮窗口View"); textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, dp2px(mContext, 15)); mLayoutParams = new WindowManager.LayoutParams(); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { mLayoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY; } else { mLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT; } mLayoutParams.format = PixelFormat.RGBA_8888; //窗口透明 mLayoutParams.gravity = Gravity.LEFT | Gravity.TOP; //窗口位置 mLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE; DisplayMetrics displayMetrics = mContext.getResources().getDisplayMetrics(); layoutY = displayMetrics.heightPixels / 2; layoutX = displayMetrics.widthPixels - textView.getMeasuredWidth(); mLayoutParams.width = WindowManager.LayoutParams.WRAP_CONTENT; mLayoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT; mLayoutParams.x = layoutX; mLayoutParams.y = layoutY; setListener(); } public void showFloatWindow(){ mWindowManager.addView(textView, mLayoutParams); } /** * 设置 悬浮窗 view 滑动事件 */ private void setListener() { if (textView != null) { textView.setOnTouchListener(new View.OnTouchListener() { private int moveX; //动画平移距离 int startX, startY; //起始点 boolean isMove; //是否在移动 long startTime; int finalMoveX; //最后通过动画将mView的X轴坐标移动到finalMoveX boolean downMove = false; @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: startX = (int) event.getX(); startY = (int) event.getY(); startTime = System.currentTimeMillis(); isMove = false; downMove = false; return false; case MotionEvent.ACTION_MOVE: //当移动距离大于2时候,刷新界面。 if (Math.abs(startX - event.getX()) > 2 || Math.abs(startY - event.getY()) > 2) { downMove = true; mLayoutParams.x = (int) (event.getRawX() - startX); mLayoutParams.y = (int) (event.getRawY() - startY); updateViewLayout(); //更新mView 的位置 } return true; case MotionEvent.ACTION_UP: long curTime = System.currentTimeMillis(); isMove = curTime - startTime > 100; if (isMove){ //判断mView是在Window中的位置,以中间为界 if (mLayoutParams.x + textView.getMeasuredWidth() / 2 >= mWindowManager.getDefaultDisplay().getWidth() / 2) { finalMoveX = mWindowManager.getDefaultDisplay().getWidth() - textView.getMeasuredWidth(); } else { finalMoveX = 0; } //使用动画移动mView animator = ValueAnimator.ofInt(mLayoutParams.x, finalMoveX).setDuration(Math.abs(mLayoutParams.x - finalMoveX)); animator.addUpdateListener((ValueAnimator animation) -> { if (animation != null) { moveX = (int) animation.getAnimatedValue(); mLayoutParams.x = (int) animation.getAnimatedValue(); updateViewLayout(); } }); animator.start(); } return isMove; } return false; } }); } } /** * 刷新 circle view 位置 */ private void updateViewLayout() { if (null != textView && null != mLayoutParams && mWindowManager != null) { try { mWindowManager.updateViewLayout(textView, mLayoutParams); } catch (Exception e) { e.printStackTrace(); } } } /** * 根据手机的分辨率从 dp 的单位 转成为 px(像素) */ public static int dp2px(Context context, float dpValue) { if (context != null) { final float scale = context.getResources().getDisplayMetrics().density; return (int) (dpValue * scale + 0.5f); } return (int) dpValue; }
2、SettingsCompat 动态权限判断(适配大部分厂商)
public class SettingsCompat { private static final int OP_WRITE_SETTINGS = 23; private static final int OP_SYSTEM_ALERT_WINDOW = 24; /** * 检查悬浮窗权限 当没有权限,跳转到权限设置界面 * * @param context 上下文 * @param isShowDialog 没有权限,是否弹框提示跳转到权限设置界面 * @param isShowPermission 是否跳转权限开启界面 * @return true 有权限 false 没有权限(跳转权限界面、权限失败 提示用户手动设置权限) * @by 腾讯云直播 悬浮框判断逻辑 */ public static boolean canDrawOverlays(Context context, boolean isShowDialog, boolean isShowPermission) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (!Settings.canDrawOverlays(context)) { if (isShowDialog) { //去授权 SettingsCompat.manageDrawOverlays(context); } else if (isShowPermission) { manageDrawOverlays(context); } return false; } return true; } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { if (checkOp(context, OP_SYSTEM_ALERT_WINDOW)) { return true; } else { if (isShowPermission) startFloatWindowPermissionErrorToast(context); return false; } } else { return true; } } /** * 打开 悬浮窗 授权界面 * * @param context */ public static void manageDrawOverlays(Context context) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { try { Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION); intent.setData(Uri.parse("package:" + context.getPackageName())); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); } catch (Exception e) { e.printStackTrace(); startFloatWindowPermissionErrorToast(context); } } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { if (!manageDrawOverlaysForRom(context)) { startFloatWindowPermissionErrorToast(context); } } } /** * 权限设置 失败提示。 * * @param context */ public static void startFloatWindowPermissionErrorToast(Context context) { if (context != null) Toast.makeText(context, "进入设置页面失败,请手动开启悬浮窗权限", Toast.LENGTH_SHORT).show(); } private static boolean manageDrawOverlaysForRom(Context context) { if (RomUtil.isMiui()) { return manageDrawOverlaysForMiui(context); } if (RomUtil.isEmui()) { return manageDrawOverlaysForEmui(context); } if (RomUtil.isFlyme()) { return manageDrawOverlaysForFlyme(context); } if (RomUtil.isOppo()) { return manageDrawOverlaysForOppo(context); } if (RomUtil.isVivo()) { return manageDrawOverlaysForVivo(context); } if (RomUtil.isQiku()) { return manageDrawOverlaysForQihu(context); } if (RomUtil.isSmartisan()) { return manageDrawOverlaysForSmartisan(context); } return false; } private static boolean checkOp(Context context, int op) { AppOpsManager manager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE); try { Method method = AppOpsManager.class.getDeclaredMethod("checkOp", int.class, int.class, String.class); return AppOpsManager.MODE_ALLOWED == (int) method.invoke(manager, op, Binder.getCallingUid(), context.getPackageName()); } catch (Exception e) { } return false; } // 可设置Android 4.3/4.4的授权状态 private static boolean setMode(Context context, int op, boolean allowed) { if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR2 || Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { return false; } AppOpsManager manager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE); try { Method method = AppOpsManager.class.getDeclaredMethod("setMode", int.class, int.class, String.class, int.class); method.invoke(manager, op, Binder.getCallingUid(), context.getPackageName(), allowed ? AppOpsManager.MODE_ALLOWED : AppOpsManager.MODE_IGNORED); return true; } catch (Exception e) { } return false; } /** * 跳转界面 * * @param context * @param intent * @return */ private static boolean startSafely(Context context, Intent intent) { List<ResolveInfo> resolveInfos = null;
