Question

我正在制作一个Android应用程序，我有4个文本视图，即ProductId，Title，description，image。我希望当我点击它们时，应该显示每个产品ID。我有一个web服务。

webservice的输出是

vmsc>
<response code="0" message="Success"/>
−
<responsedata>
−
<productcategories>
−
<productcategory>
<id>1</id>
<title>Celebrities</title>
<description>Celebrities</description>
<image>
        </image>
</productcategory>
−
<productcategory>
<id>2</id>
<title>Music</title>
<description>Music</description>
<image>
        </image>
</productcategory>

<productcategory>
<id>3</id>
<title>Sports</title>
<description>Sports</description>

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

您只需创建OnClickListeners文字视图，例如：

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

此点击监听器有效：

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());
                }
            }
        });

声明文本视图时不引用android:clickable="true"（默认向导）：

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

在android中使textview可点击
