今天学习了TelephonyManager(电话管理器)。

布局文件为：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="5dp"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/tv_phone1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/tv_phone2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/tv_phone3"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/tv_phone5"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/tv_phone6"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/tv_phone7"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

</LinearLayout>

 主要代码：

public class MainActivity extends AppCompatActivity {

    private TelephonyManager tManager;
    private String[] phoneType = {"未知","2G","3G","4G"};
    private String[] simState = {"状态未知","无SIM卡","被PIN加锁","被PUK加锁",
            "被NetWork PIN加锁","已准备好"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //①获得系统提供的TelphonyManager对象的实例
        tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        bindViews();
    }

    private void bindViews() {
        tv_phone1 = (TextView) findViewById(R.id.tv_phone1);
        tv_phone2 = (TextView) findViewById(R.id.tv_phone2);

        tv_phone8 = (TextView) findViewById(R.id.tv_phone8);
        tv_phone9 = (TextView) findViewById(R.id.tv_phone9);

        tv_phone1.setText("设备编号：" + tManager.getDeviceId());
        tv_phone2.setText("软件版本：" + (tManager.getDeviceSoftwareVersion()!= null?

                .getCellLocation().toString() : "未知位置"));
        tv_phone7.setText("SIM卡的国别：" + tManager.getSimCountryIso());
        tv_phone8.setText("SIM卡序列号：" + tManager.getSimSerialNumber());
        tv_phone9.setText("SIM卡状态：" + simState[tManager.getSimState()]);
    }
}
