问题描述
我想我的变量添加到网页视图。举例来说,我不希望是:http:// example.com,但是,我想MYVARIABLE。
我的code是:
公共类经理扩展活动{
EDITTEXT的EditText; @覆盖
保护无效的onCreate(捆绑savedInstanceState){
// TODO自动生成方法存根
super.onCreate(savedInstanceState);
的setContentView(R.layout.manager);
的WebView =(的WebView)findViewById(R.id.webview);
// Instanciation杜的WebView ...
的WebView wvSite =(的WebView)findViewById(R.id.webview); //...on活跃的JavaScript ...
WebSettings webSettings = wvSite.getSettings();
webSettings.setJavaScriptEnabled(真); //...et电荷拉页
wvSite.loadUrl(http://example.com);
loadSaved preferences();
}
私人无效loadSaved preferences(){
共享preferences共享preferences = preferenceManager
.getDefaultShared preferences(本); 字符串名称=共享preferences.getString(storedName,提供yourname); editText.setText(名);
}}
和我想通过变量名来替换mysite.com。
可能吗?而如何?

是的。首页发现您的EditText(中的onCreate),那么你可以使用它。结果
这样的:
EDITTEXT =(EditText上)findViewById(R.id.edittext);
或者,你会得到一个NullPointerException异常。
然后地方(在按钮的点击监听器,例如):
wvSite.loadUrl(editText.getText()的toString());
在换句话说:
@覆盖
保护无效的onCreate(捆绑savedInstanceState){
// TODO自动生成方法存根
super.onCreate(savedInstanceState);
的setContentView(R.layout.manager);
//添加此行
EDITTEXT =(EditText上)findViewById(R.id.edittext); 的WebView =(的WebView)findViewById(R.id.webview);
// ... //跳过此行
//wvSite.loadUrl(\"http://example.com);
当你wanto加载页面:
字符串someURL =http://www.google.com
wvSite.loadUrl(someURL);
记住必须有一些有效的URL在你的EditText ,为了您的WebView加载任何
I want to add my variable to the webview. For example, I don't want : http:// example.com but, I want myvariable. My code is :
public class manager extends Activity{
EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.manager);
WebView = (WebView) findViewById(R.id.webview);
// Instanciation du WebView...
WebView wvSite = (WebView)findViewById(R.id.webview);
//...on active JavaScript...
WebSettings webSettings = wvSite.getSettings();
webSettings.setJavaScriptEnabled(true);
//...et on charge la page
wvSite.loadUrl("http://example.com");
loadSavedPreferences();
}
private void loadSavedPreferences() {
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(this);
String name = sharedPreferences.getString("storedName", "YourName");
editText.setText(name);
}
}
And I want to replace mysite.com by the variable name. Is it possible? and How?
Edit :
public class manager extends Activity{
EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.manager);
editText = (EditText) findViewById(R.id.edittext);
// Instanciation du WebView...
WebView wvSite = (WebView)findViewById(R.id.webview);
//...on active JavaScript...
WebSettings webSettings = wvSite.getSettings();
webSettings.setJavaScriptEnabled(true);
//...et on charge la page
wvSite.loadUrl(editText.getText().toString());
loadSavedPreferences();
}
private void loadSavedPreferences() {
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(this);
String name = sharedPreferences.getString("storedName", "YourName");
editText.setText(name);
}
}
Yes. First find your EditText (in onCreate), then you can use it.
Like:
editText = (EditText) findViewById(R.id.edittext);
Or you will get a NullPointerException.
Then somewhere (in the click listener of a button, for instance):
wvSite.loadUrl(editText.getText().toString());
In other words:
@Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.manager);
// Add this line
editText = (EditText) findViewById(R.id.edittext);
WebView = (WebView) findViewById(R.id.webview);
// ...
// skip this line
//wvSite.loadUrl("http://example.com");
When you wanto to load the page:
String someURL = "http://www.google.com";
wvSite.loadUrl(someURL);
Mind that there must be some valid URL in your EditText, in order for your WebView to load anything
