Android 中如何挂断去电

Android中如何挂断去电？

检测来电状态

java
public class MyPhoneStateListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        super.onCallStateChanged(state, incomingNumber);
        
        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE: // 无任何状态
                // 在这里处理挂断去电的逻辑
                break;
            case TelephonyManager.CALL_STATE_RINGING: // 来电响铃
                // 在这里处理来电响铃的逻辑
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话
                // 在这里处理接听电话的逻辑
                break;
        }
    }
}

挂断去电

java
public class MainActivity extends AppCompatActivity {
    private TelephonyManager telephonyManager;
    private MyPhoneStateListener phoneStateListener;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        phoneStateListener = new MyPhoneStateListener();
        telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);
    }
    private void endCall() {
        try {
            Class telephonyManagerClass = TelephonyManager.class;
            Method method = telephonyManagerClass.getDeclaredMethod("getITelephony");
            method.setAccessible(true);
            Object telephonyService = method.invoke(telephonyManager);
            Class telephonyServiceClass = telephonyService.getClass();
            Method endCallMethod = telephonyServiceClass.getDeclaredMethod("endCall");
            endCallMethod.invoke(telephonyService);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
