Webview is a very simple function. The code is not logically difficult, but you need to pay attention to permissions. In fact, during the Android programming process, permission problems can be regarded as a relatively large number of bugs.
package .webview01;
import ;
import ;
import ;
import ;
import ;
import ;
import ;

import ;
import ;
public class MainActivity extends Activity {
private EditText et_url;
private Button btn_request;
private WebView wv;
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_main);
initView();
initSetting();
initEvent();
}
private void initSetting() {
//webview setting properties WebSettings ws=();
(true);
();
(true);
(true);
//Click the link to continue to respond in the current browser, rather than responding to the link in the newly opened Android system browser. You must override the webview WebViewClient object (new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
(url);
return true;
}
});
}
//Initialize the control private void initView() {
et_url =(EditText)findViewById(.et_url);
btn_request = (Button)findViewById(.btn_request);
wv= (WebView)findViewById();
}
//Key monitoring public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && ()) {
();
return true;
}
return (keyCode, event);
}
//Initialize event private void initEvent() {
btn_request.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String url=et_url.getText().toString().trim();
(url);
}
});
}
}
2. The most important thing is to add permissions in the manifest, otherwise it will not be displayed.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:andro
package=".webview01"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<uses-permission android:name=""/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="."
android:label="@string/app_name" >
<intent-filter>
<action android:name="" />
<category android:name="" />
</intent-filter>
</activity>
</
app````

</manifest>
