Answer 1

final TextView view = (TextView) findViewById(R.id.textview1);
view.setOnClickListener(new View.OnClickListener() {

  @Override
  public void onClick(View v) {
    // request your webservice here. Possible use of AsyncTask and ProgressDialog
    // show the result here - dialog or Toast
  }

});

you can also do it using xml like

      <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="handleOnClick"
        android:clickable="true"
        android:text="Clickable TextView"
        android:textSize="30sp" />

and handle onClick like

public void handleOnClick(View view)
{
   switch(view.getId())
   { 
      case R.id.textView:
      //do your stufff here..
      break;
      default: 
      break;
   }
}

Answer 3

You can simply create OnClickListeners of your textviews like:

TextView textview = new TextView(this);
        textview.setText("This is a textview");

        textview.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // do something here.
            }
        });

Answer 4

this click listener works:

setContentView(R.layout.your_layout);
TextView tvGmail = (TextView) findViewById(R.id.tvGmail);
String TAG = "yourLogCatTag";
tvGmail.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View viewIn) {
                try {
                    Log.d(TAG,"GMAIL account selected");
                } catch (Exception except) {
                    Log.e(TAG,"Ooops GMAIL account selection problem "+except.getMessage());
                }
            }
        });

the text view is declared with no reference to android:clickable="true" (default wizard):

        <TextView
            android:id="@+id/tvGmail"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/menu_id_google"
            android:textSize="30sp" />
