android - 更换 SIM 卡时的事件

Question

手机换卡时如何访问事件？

Answer 1

基本上，这个问题“How to monitor SIM state change”的答案也是您问题的正确答案。

所以你创建了一个新类

package a.b.c;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class SimChangedReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {

         Log.d("SimChangedReceiver", "--> SIM state changed <--");

        // Most likely, checking if the SIM changed could be limited to
        // events where the intent's extras contains a key "ss" with value "LOADED".
        // But it is more secure to just always check if there was a change.
    }
}

并调整您的 AndroidManifest.xml 以包含

<!-- put this where your other permissions are: -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<!-- and -->
<application
    android:name="a.b.c...."
    ... >
    <!-- put this somewhere into your application section: -->
    <receiver android:name="a.b.c.SimChangedReceiver">
        <intent-filter>
            <action android:name="android.intent.action.SIM_STATE_CHANGED"/>
        </intent-filter>
    </receiver>
</application>

像往常一样，在 Android 上，不保证它在任何版本或任何制造商的设备上都能正常工作。
