Android中的可点击TextView [英] Clickable TextView in Android

问题描述

我正在构建一个 Android 应用程序，其中包含许多我希望可点击的 TextView.我试图将属性 android:clickable="true" 和 android:onClick="clickHandler" 分配给单个 TextView 以及何时应用程序触发 clickHandler(View v) 我通过 v.getId() 正确获取点击的项目.我不喜欢为每个 TextView 定义属性 android:clickable 和 android:onClick ... 有什么我可以通过代码说:所有文本视图都是可点击的，点击是在 clickHandler 中处理的?"

I'm building an Android App that has many many TextViews that I want to be clickable. I've tried to assign the properties android:clickable="true" and android:onClick="clickHandler" to the single TextView and when the app fires the clickHandler(View v) I get the clicked item correctly through v.getId(). What I don't like is to define, for every TextView, the properties android:clickable and android:onClick ... is there something that i can do by code to say: "all the textviews are clickable and click is handled in clickHandler ?"

谢谢.

推荐答案

你可以在下面做这样的事情 - 这样他们都有相同的处理程序:

You could do something like this below - this way they all have the same handler:

public class sticks extends Activity implements View.OnTouchListener { 
  private TextView tv1; 
  private TextView tv2;
  private TextView tv3;

  @Override 
  public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    tv1 = (TextView) findViewById(R.id.tv1); 
    tv2 = (TextView) findViewById(R.id.tv2); 
    tv3 = (TextView) findViewById(R.id.tv3); 

    // bind listeners
    tv1.setOnTouchListener(this); 
    tv2.setOnTouchListener(this); 
    tv3.setOnTouchListener(this); 

  } 

  @Override 
  public boolean onTouch(View v, MotionEvent event) { 
    // check which textview it is and do what you need to do

    // return true if you don't want it handled by any other touch/click events after this
    return true; 
  } 
}
