公共 class MainActivity 扩展 AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final EditText editText = (EditText) findViewById(R.id.etext) ;
    webView.setWebViewClient (new WebViewClient() ); 
    Button button = (Button)findViewById(R.id.btn_go) ;
    button.setOnClickListener (new View.OnClickListener() {
        @Override
        public void onClick (View v){
            webView.loadUrl(editText.getText().toString() ) ;
        }
    });

}

}
