线性布局

我正在尝试LinearLayout在主屏幕上创建一个作为菜单。我不想Buttons或不必创建图像，我喜欢使用TextViewsand获得的外观Layouts。我的问题是我无法onClick()通过第一个布局工作，过去几天它让我发疯。有什么小东西我错过了还是我做错了？

主.Java

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;



public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

            LinearLayout computer = (LinearLayout) findViewById(R.id.main_btn_computer);
            LinearLayout networking = (LinearLayout) findViewById(R.id.main_btn_networking);

            computer.setOnClickListener(new OnClickListener()
            {
                  public void onClick(View v) {
              //Call your method here
                          startActivity (new Intent(getApplicationContext(), ComputerMain.class));        
                      }

            });

          networking.setOnClickListener(new OnClickListener()
            {
                  public void onClick(View v) {
              //Call your method here 
                          startActivity (new Intent(getApplicationContext(), NetworkingMain.class));  
                      }

            });
          }
    }
    }

主.xml

为什么要使用onClickFeature(View v)它的onClick(View v).

正在设置你的onClickListener()?

致电您的LinearLayout

LinearLayout computer = (LinearLayout) findViewById(R.id.main_btn_computer);
LinearLayout networking = (LinearLayout) findViewById(R.id.main_btn_networking);

设置 onClick 监听器

computer.setOnClickListener(new OnClickListener()
  {
        public void onClick(View v) {
    //Call your method here
                startActivity (new Intent(getApplicationContext(), ComputerMain.class));        
            }

  });

networking.setOnClickListener(new OnClickListener()
  {
        public void onClick(View v) {
    //Call your method here 
                startActivity (new Intent(getApplicationContext(), NetworkingMain.class));  
            }

  });

删除android:onClick=""属性
