如何将textview转换为android中的链接？

Question

我创建了一个登录页面，其中包含用户名密码登录按钮和一个应该是链接的注册按钮。我想将此注册（文本视图）转换为可以导航到下一页的链接。我该怎么办？例如，如果我点击没有帐户？ sigup ，它应该导航到welcome.java ..

请帮忙......

}

Answer 1

试试这个：

package com.example.internationalization12;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends Activity {

TextView txtSignUp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         txtSignUp=(TextView)findViewById(R.id.txt_sign_up);
         txtSignUp.setText(Html.fromHtml("<u>Dont have account?SignUp</u>")
         txtSignUp.setOnClickListener(signUpListener);
        //getActionBar().hide();
    }
    public OnClickListener signUpListener=new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
          startActivity(new Intent(MainActivity.this,Welcome.class));
        }
    };

}

您可以尝试Linkify here

textview.setText("www.androiddeveloper.com");
Linkify.addLinks(textview, Linkify.WEB_URLS);

Answer 3

您必须将setOnTouchListener设置为TextView。我在这里举个例子：

    public class MainActivity extends Activity implements View.OnTouchListener { 
      private TextView tv1; 

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

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

        tv1.setOnTouchListener(this); 

      } 

      @Override 
      public boolean onTouch(View v, MotionEvent event) { 

       // HERE YOU HAVE TO CHECK WHICH ID IS SELECTED, IF YOU HAVE MORE THAN ONE,
       //   AND WHICH EVENT HAS THE USER DONE.

      // IN YOUR CASE.. OPEN WEBSITE LIKE THIS:


Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

        return true; 
      } 
    }
