最简单的webView使用

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Toast;

public class MainActivity extends Activity {
	private String TAG = "HIPPO_DEBUG";
	private ImageButton mImageButton01;
	private EditText mEditText;
	private WebView mWebView1;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		mImageButton01 = (ImageButton) findViewById(R.id.myImageButton1);
		mEditText = (EditText) findViewById(R.id.myEditText1);
		mEditText.setText("http://baidu.com");
		mWebView1 = (WebView) findViewById(R.id.myWebView1);
		mWebView1.setWebViewClient(new WebViewClient());
		mImageButton01.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				mImageButton01.setImageResource(R.drawable.go_2);
				String URL = mEditText.getText().toString();
				mWebView1.loadUrl(URL);
				Log.i(TAG, "loadURL");
				Toast.makeText(MainActivity.this,
						getString(R.string.load) + URL, Toast.LENGTH_LONG)
						.show();
			}
		});
	}
