如何在Android中单击textview [英] how to click on textview in android

问题描述

单击文本视图不起作用

我的xml是

 < TextViewandroid:id ="@ + id/button2"android:layout_width ="wrap_content"android:layout_height ="fill_parent"android:layout_marginLeft ="5dp"android:layout_weight ="3"android:gravity ="center"android:textColor ="@ color/white"android:text =点击下载sevenstepstocollege"android:textSize ="15dp"android:onClick ="downloadLink"android:clickable ="true"></TextView> 

我的活动代码是

 公共无效下载链接(查看v){//字符串requestId = PurchasingManager.initiatePurchaseRequest(skuKye);//String requestId = PurchasingManager.initiateItemDataRequest("DeveloperSKU-1234");skuSet.add(skuKye);最终的字符串requestId = PurchasingManager.initiateItemDataRequest(skuSet);} 

但是它不起作用.我无法单击该链接.请指导我

解决方案

好，我使用以下代码使TextView可点击.

首先，将其添加到您的activity.xml中，以使TextView易于使用:

 < TextViewandroid:id = android:id ="@ + id/button2"<！-id来获取此TextView->(...)android:onClick ="onClick"<！-添加功能onClick()->android:clickable ="true"<！-将布尔型clickable设置为true->/> 

然后，在MainActivity.java中，添加:

  private TextView textview;@Override受保护的void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//通过id获取TextViewtextview =(TextView)findViewById(R.id.button2);textview.setOnClickListener(new View.OnClickListener(){@Overridepublic void onClick(View v){//点击链接时的待办事项(TextView)}});} 

正如我现在所看到的那样，您正在尝试使TextView中的链接可单击，而不仅仅是能够单击TextView.我将让下面的链接指向在Stack Overflow中解决的类似问题，您可能会发现有帮助./p>

Click on text view is not working

My xml is

<TextView
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginLeft="5dp"
android:layout_weight="3"
android:gravity="center" 
android:textColor="@color/white"
android:text="click to download sevenstepstocollege"
android:textSize="15dp"
android:onClick="downloadLink"
android:clickable="true">
</TextView>

and My Activity code is

public void downloadLink(View v)
{
//String requestId = PurchasingManager.initiatePurchaseRequest(skuKye);
//String requestId=PurchasingManager.initiateItemDataRequest("DeveloperSKU-1234");
skuSet.add(skuKye);
final String requestId = PurchasingManager.initiateItemDataRequest(skuSet);
}  

But it is not working.I am not able to click that link.please guide me

解决方案

Well, I use the following code to make a TextView clickable.

First, add this at your activity.xml, to make TextView clikable:

<TextView
    android:id=android:id="@+id/button2" <!-- id to get this TextView -->
    (...)
    android:onClick="onClick"  <!-- Add the function onClick() -->
    android:clickable="true"   <!-- Set the boolean clickable to true -->
/>

Then, at your MainActivity.java, you add:

private TextView textview;    

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);    
    setContentView(R.layout.activity_main);  

    // Get the TextView by id
    textview = (TextView) findViewById(R.id.button2);

    textview.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
              // TODO when clicked on your link(TextView)
        }
    });
}

As I see now that you are trying to make a link from the TextView clickable, not just be able to click on the TextView I will let a link below to a similar question solved in Stack Overflow that you might find helpful.
