在if/else上错过了a｝和/或)

Question

我在代码末尾错过了一个}和/或），我试了很多次，但都没有得到，有人知道吗？

        doclink.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
            if(!uri.contains("https://www.facebook.com/")) {  
              String natgeo = "natgeo";  
              String uri = "fb://Page/" + natgeo;      
              Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));  
              startActivity(intent);     
              }  
            else{  
              String natgeo = "natgeo";  
              String uri = "https://www.facebook.com/" + natgeo;    
              Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));      
              startActivity(i);   
    }
};

Answer 1

doclink.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
            if(!uri.contains("https://www.facebook.com/")) {  
              String natgeo = "natgeo";  
              String uri = "fb://Page/" + natgeo;      
              Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));  
              startActivity(intent);     
              }  
            else{  
              String natgeo = "natgeo";  
              String uri = "https://www.facebook.com/" + natgeo;    
              Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));      
              startActivity(i);   
            }
    }
});

更新：

您可以像下面的代码一样实现OnClickListener：

public class MainActivity extends Activity {
Button dadclink;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    dadclink = (Button) findViewById(R.id.dadclink);
    dadclink.setOnClickListener(myClickListener);
}
private View.OnClickListener myClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        switch(v.getId()){
          case R.id.dadclink:
            if(!uri.contains("https://www.facebook.com/")) {  
              String natgeo = "natgeo";  
              String uri = "fb://Page/" + natgeo;      
              Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));  
              startActivity(intent);     
            }  
            else{  
              String natgeo= "natgeo";  
              String uri = "https://www.facebook.com/" + natgeo;    
              Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));      
              startActivity(i);   
            }
           break;
        }
   } 
};
}

更新2:

private View.OnClickListener myClickListener = new View.OnClickListener() {
    final String uri = null;
    @Override
    public void onClick(View v) {
        switch(v.getId()){
          case R.id.dadclink:
              String natgeo= "natgeo";  
              String uri = "https://www.facebook.com/" + natgeo;    
              Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));      
              startActivity(i);
           break;
        }
   } 
};

并记住将这一行添加到您的manifest.xml文件中：

<activity
        android:name=".MainActivity"
 ....
<intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
 ...
</activity>

Answer 2

您正在创建一个匿名内部类，您的最后一行-

    startActivity(i);   
  }
};

应该是

    startActivity(i);   
  }
}); // <-- close the open paren.

编辑

根据你的评论，我建议你把它提取到一个类-

class MyListener extends OnClickListener() {
  @Override
  public void onClick(View arg0) {
    String natgeo = "natgeo";          
    String uri = (!uri.contains("https://www.facebook.com/")) ?
         "fb://Page/" : "https://www.facebook.com/";
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri+natgeo));
    startActivity(intent);     
  }
}

然后

doclink.setOnClickListener(new MyListener());

Answer 3

doclink.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (!uri.contains("https://www.facebook.com/")) {
                    String natgeo = "natgeo";
                    String uri = "fb://Page/" + natgeo;
                    Intent intent = new Intent(Intent.ACTION_VIEW, Uri
                            .parse(uri));
                    startActivity(intent);
                } else {
                    String natgeo = "natgeo";
                    String uri = "https://www.facebook.com/" + natgeo;
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
                    startActivity(i);
                }
            }
        });
