Android 错误：（22，30）错误：不兼容类型：无法将对象转换为传感器

我试图显示设备中可用的传感器…这是我的代码，我很难知道该怎么做

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.hardware.Sensor;
import android.hardware.SensorManager;
import android.widget.TextView;

import java.util.List;

public class MainActivity extends AppCompatActivity {
    private SensorManager sMgr;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView sensorsData = (TextView) findViewById(R.id.textView1);
        sMgr = (SensorManager) this.getSystemService(SENSOR_SERVICE);
        List list = sMgr.getSensorList(Sensor.TYPE_ALL);
        StringBuilder data = new StringBuilder();
        for (Sensor sensor : list) {
            data.append(sensor.getName() + "\n");
            data.append(sensor.getVendor() + "\n");
            data.append(sensor.getVersion() + "\n");
        }
        sensorsData.setText(data);
    }
}

错误就在这一行

for (Sensor sensor : list) {

使用

使用

列表=

？

列表=

？

List<Sensor> list = sMgr.getSensorList(Sensor.TYPE_ALL);

List list = sMgr.getSensorList(Sensor.TYPE_ALL);
