问题描述
我正在通过此活动将数据发送到另一个活动
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText etxt=(EditText)findViewById(R.id.editText1);
final EditText etxt1=(EditText)findViewById(R.id.editText2);
Button btn=(Button)findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String s= etxt.getText().toString();
String s1= etxt1.getText().toString();
Intent intent= new Intent(getApplicationContext(),WebActivity.class);
intent.putExtra("key", s);
intent.putExtra("key1", s1);
}
});
}
}
我的第二项活动是从意图中接收数据，并希望将其显示在网络视图中.
public class WebActivity extends Activity {
WebView webView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webpage);
Bundle b = getIntent().getExtras();
String s = b.getString("key");
String s1=b.getString("key1");
webView=(WebView)findViewById(R.id.webview);
}
}
在Google上进行的一些搜索中，我发现可以使用javascript变量来完成此操作，但我不知道该怎么做.请回答.
From some searching on Google i found that it can be accomplished by using javascript variables but I dont know how to do it. Kindly answer.
推荐答案
Did you checked Android WebView documentation?
// Simplest usage: note that an exception will NOT be thrown
// if there is an error loading this page (see below).
webview.loadUrl("http://slashdot.org/");
// OR, you can also load from an HTML string:
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", null);
// ... although note that there are restrictions on what this HTML can do.
// See the JavaDocs for loadData() and loadDataWithBaseURL() for more info.
