安卓开发做一款可以将ping出来的丢包率展示在textview上

您可以使用以下代码将ping出来的丢包率展示在textview上：

try {
    String pingCommand = "/system/bin/ping -c 4 " + ipAddress;
    Runtime runtime = Runtime.getRuntime();
    Process process = runtime.exec(pingCommand);
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

    StringBuilder log = new StringBuilder();
    String line;
    while ((line = bufferedReader.readLine()) != null) {
        log.append(line + "\n");
    }

    textView.setText(log.toString());
} catch (IOException e) {
    e.printStackTrace();
}

其中，ipAddress是您要ping的IP地址。

在Android Studio中，实现将edittext中输入要ping的ip地址，点击button开始执行，执行的丢包率展示在textview上

可以使用以下代码实现：

public class MainActivity extends AppCompatActivity {
    private EditText editText;
    private Button button;
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = findViewById(R.id.editText);
        button = findViewById(R.id.button);
        textView = findViewById(R.id.textView);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String ip = editText.getText().toString();
                try {
                    Process p = Runtime.getRuntime().exec("ping -c 4 " + ip);
                    BufferedReader inputStream = new BufferedReader(new InputStreamReader(p.getInputStream()));
                    String result = "";
                    String line;
                    while ((line = inputStream.readLine()) != null) {
                        result += line + "\n";
                    }
                    textView.setText(result);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });
    }
}

其中，editText是输入IP地址的EditText，button是点击开始执行的Button，textView是展示丢包率的TextView。在button的点击事件中，使用Runtime.getRuntime().exec()方法执行ping命令，并将结果展示在textView中。

安卓开发开发一款可以获取实时gps信号的经纬度和4g/5g网络质量和网络以及实现ping其他ip并将丢包率展示的软件

这个问题需要使用 Android 的 LocationManager 和 ConnectivityManager 类来获取 GPS 和网络信息，使用 Ping 命令来测试网络连接并计算丢包率。以下是一个简单的示例代码：

public class MainActivity extends AppCompatActivity {

    private LocationManager locationManager;
    private ConnectivityManager connectivityManager;
    private TextView gpsTextView;
    private TextView networkTextView;
    private TextView pingTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 获取 LocationManager 和 ConnectivityManager 实例
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

        // 获取 UI 控件
        gpsTextView = findViewById(R.id.gpsTextView);
        networkTextView = findViewById(R.id.networkTextView);
        pingTextView = findViewById(R.id.pingTextView);

        // 请求 GPS 权限
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
        } else {
            startLocationUpdates();
        }

        // 每隔 5 秒钟更新一次网络信息和 Ping 命令结果
        new Timer().scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {
                updateNetworkInfo();
                updatePingResult();
            }
        }, 0, 5000);
    }

    // 开始获取 GPS 位置信息
    private void startLocationUpdates() {
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                // 更新 GPS 位置信息
                gpsTextView.setText(String.format("经度：%f，纬度：%f", location.getLongitude(), location.getLatitude()));
            }

            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {}

            @Override
            public void onProviderEnabled(String provider) {}

            @Override
            public void onProviderDisabled(String provider) {}
        });
    }

    // 更新网络信息
    private void updateNetworkInfo() {
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.isConnected()) {
            // 更新网络类型和信号强度
            String networkType = networkInfo.getTypeName();
            int signalStrength = getSignalStrength(networkInfo.getType());
            networkTextView.setText(String.format("%s，信号强度：%d", networkType, signalStrength));
        } else {
            networkTextView.setText("无网络连接");
        }
    }

    // 获取网络信号强度
    private int getSignalStrength(int networkType) {
        if (networkType == ConnectivityManager.TYPE_WIFI) {
            WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            return wifiInfo.getRssi();
        } else if (networkType == ConnectivityManager.TYPE_MOBILE) {
            TelephonyManager telephonyManager = (TelephonyManager) getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
            CellInfo cellInfo = telephonyManager.getAllCellInfo().get(0);
            if (cellInfo instanceof CellInfoGsm) {
                CellSignalStrengthGsm gsmSignalStrength = ((CellInfoGsm) cellInfo).getCellSignalStrength();
                return gsmSignalStrength.getDbm();
            } else if (cellInfo instanceof CellInfoLte) {
                CellSignalStrengthLte lteSignalStrength = ((CellInfoLte) cellInfo).getCellSignalStrength();
                return lteSignalStrength.getDbm();
            } else {
                return 0;
            }
        } else {
            return 0;
        }
    }

    // 更新 Ping 命令结果
    private void updatePingResult() {
        try {
            Process process = Runtime.getRuntime().exec("ping -c 5 8.8.8.8");
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            int received = 0;
            int lost = 0;
            while ((line = reader.readLine()) != null) {
                if (line.contains("received")) {
                    received = Integer.parseInt(line.split(" ")[3]);
                    lost = Integer.parseInt(line.split(" ")[6]);
                }
            }
            reader.close();
            pingTextView.setText(String.format("丢包率：%d%%", lost * 100 / (received + lost)));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
