自定义ViewPager+WebView跳转

1.MainAdapter

//视图调用

package com.bwie.skn.customviewpagerdemo2;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Toast;

import com.bwie.skn.customviewpagerdemo2.view.CustomViewPagerClass;

public class MainActivity extends AppCompatActivity {
    private CustomViewPagerClass cvp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        cvp = (CustomViewPagerClass) findViewById(R.id.cvp);
        cvp.setOnClick(new CustomViewPagerClass.onClickListener() {
            @Override
            public void onGoWebView(View v, String url, String type) {
                if(type.trim().equals("0")){
                    Intent intent = new Intent(MainActivity.this,WebViewActivity.class);
                    intent.putExtra("url",url);
                    startActivity(intent);
                }else{
                    Toast.makeText(MainActivity.this,"我要跳转页面",Toast.LENGTH_SHORT).show();
                }
            }
        });
    }
}
