我在MainActivity中有两个活动MainActivity.java和WebViewActivity.java,它有一个edittext和一个按钮。现在我想如果我在edittext中输入任何字符串,并且在按钮单击后它应该将该字符串传递到WebViewActivity中的url,如www.mywebsite.com + getTestFromEdittext
MainActivity.java
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText inputUrl = (EditText) findViewById(R.id.editText1);
Button button = (Button)findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this, WebViewActivity.class);
startActivity(intent);
}
});
}
}
WebViewActivity.java
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.php);
WebView wb = (WebView)findViewById(R.id.webview);
wb.loadUrl("http://example.com" + getStringFromEdittext);
wb.getSettings().setJavaScriptEnabled(true);
}
}
答案 0 :(得分:2)
启动活动时使用此代码:
MainActivity:
Intent intent = new Intent(MainActivity.this, WebViewActivity.class);
intent.putExtra("text", inputUrl.getText().toString());
startActivity(intent);
获取值:
WebViewActivity:
String getStringFromEdittext = getIntent().getExtras().getInt("text");
