android监听SD卡状态

步骤1、创建一个广播类

public class SdReceiver extends BroadcastReceiver {    private String TAG = "TfReceiver";    @Override    public void onReceive(Context context, Intent intent) {        String action = intent.getAction();        switch (action) {            //卡已经成功挂载            case "android.intent.action.MEDIA_MOUNTED":                String path = StoragePathUtil.getInstance().getPath(true);                Log.d(TAG, "onReceive: MEDIA_MOUNTED--" + path);                break;            //卡未挂载            case "android.intent.action.MEDIA_EJECT":            case "android.intent.action.MEDIA_REMOVED":            case "android.intent.action.ACTION_MEDIA_UNMOUNTED":            case "android.intent.action.ACTION_MEDIA_BAD_REMOVAL":                Log.d(TAG, "onReceive: 未挂载");                break;            //开始扫描            case "android.intent.action.MEDIA_SCANNER_STARTED":                Log.d(TAG, "onReceive: 开始扫描...");                break;            //扫描完成            case "android.intent.action.MEDIA_SCANNER_FINISHED":                Log.d(TAG, "onReceive: 扫描完成...");                break;            case "android.intent.action.MEDIA_SHARED":                Log.d(TAG, "onReceive: USB大容量存储被共享...");                break;        }    }}

步骤2、在AndroidManifest中注册静态监听（动态的也可以）

        <receiver android:name=".receiver.TfReceiver">            <intent-filter android:priority="1000">                <action android:name="android.intent.action.MEDIA_MOUNTED" />                <action android:name="android.intent.action.MEDIA_EJECT" />                  <action android:name="android.intent.action.MEDIA_REMOVED" />                <action android:name="android.intent.action.ACTION_MEDIA_UNMOUNTED" />                <action android:name="android.intent.action.ACTION_MEDIA_BAD_REMOVAL" />                <action android:name="android.intent.action.MEDIA_SCANNER_STARTED" />                <action android:name="android.intent.action.MEDIA_SCANNER_FINISHED" />                <action android:name="android.intent.action.MEDIA_SHARED" />                <data android:scheme="file"/>            intent-filter>        receiver>

插入是监听android.intent.action.MEDIA_MOUNTED
拔出是监听android.intent.action.MEDIA_EJECT

主要记录下要注册

<data android:scheme="file"/>

不加监听不到。。
