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 
    } 

}); 

Answer 2

您可以简单地创建textviews的OnClickListeners像：

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

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

Answer 3

这个点击监听器的工作原理：

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()); 
       } 
      } 
     }); 

文本视图声明没有提到android:clickable="true"（默认的向导）：

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

Answer 4

，你也可以做使用XML像

 <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" /> 

和处理它onClick like

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