List of available sensors on Android

You can obtain the list of available sensors on your device by calling sensonManager.getSensorList() and providing the type Sensor.TYPE_ALL as a parameter. Find below a full example.

main.xml

main.java

package com.blog.sensorslist;

import java.util.List;

import android.app.ListActivity;
import android.hardware.Sensor;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class main extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // setContentView(R.layout.main);
        
        // create new SensorManager
        SensorManager sensorManager = (SensorManager) this.getSystemService(SENSOR_SERVICE);
        // get all sensors of all types
        List sensorList = sensorManager.getSensorList(Sensor.TYPE_ALL);
        // list of all sensor types
        String[] sensorTypes = new String[]{"","ACCELEROMETER", "MAGNETIC_FIELD", 
          "ORIENTATION", "GYROSCOPE", "LIGHT", "PRESSURE","TEMPERATURE", 
          "PROXIMITY", "GRAVITY", "LINEAR_ACCELERATION", "ROTATION_VECTOR"};
        
        // array for ListAdapter
        String[] infoList = new String[sensorList.size()];
        
        for (int i =0; i < sensorList.size(); i++){
         Sensor currentSensor = sensorList.get(i);
         infoList[i] = "Sensor Name: "+ currentSensor.getName() +"\n" +
             "Vendor: "+ currentSensor.getVendor() + "\n" +
             "Version: "+ currentSensor.getVersion()+ "\n"+
             "Type: "+ currentSensor.getType() + " - "+sensorTypes[currentSensor.getType()]+ "\n"+
             "Maximum Range: "+ currentSensor.getMaximumRange()+ "\n"+
             "Power (mA):"+ currentSensor.getPower()+ "\n"+
             "Resolution: "+ currentSensor.getResolution();              
        }
        // setting the ListAddapter
        setListAdapter(new ArrayAdapter(this, R.layout.main, infoList));
    }
}

How to create a listview with custom adapter on Android

To create a ListView with your custom layout you need to create a custom adapter, override the getView method, and set the list adapter.
Find below an example with a TextView, ImageView and Button in the layout.
















main.xml

main.java

package com.blog.listviewwithcustomadapter;

import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class main extends ListActivity {

 public final String[] Colors = { "Blue", "Green", "Black" };

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  // setContentView(R.layout.main);
  // instantiate our custom adapter
  MyCustomAdapter adapter = new MyCustomAdapter(this, R.layout.main, Colors);
  //setting the adapter
  setListAdapter(adapter);
 }

 public class MyCustomAdapter extends ArrayAdapter {

  public MyCustomAdapter(Context context, int textViewResourceId, String[] list) {
   super(context, textViewResourceId, list);
  }

  @Override
     public View getView(int position, View convertView, ViewGroup parent) {
            
      View row = convertView;

      if (row == null) {
       LayoutInflater inflater = getLayoutInflater();
       row = inflater.inflate(R.layout.main, parent, false);
      }
      final int itemPosition = position;
      
      TextView listItem = (TextView) row.findViewById(R.id.colors );
      listItem.setText(Colors[position]);
      
      ImageView image = (ImageView) row.findViewById(R.id.imgAndroid);
      image.setImageResource(R.drawable.icon);
      
      Button btn = (Button) row.findViewById(R.id.btnColor);
      btn.setOnClickListener( new View.OnClickListener() {
    
    @Override
    public void onClick(View v) {
     Toast.makeText(getApplicationContext(), "Toast from button"+ Colors[itemPosition], Toast.LENGTH_SHORT).show();     
    }
   });
            
      row.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
        Toast.makeText(getApplicationContext(), Colors[itemPosition], Toast.LENGTH_SHORT).show();
       }     
      });
      return row;
     }
 }
}
