我正在为我的书制作一个 Android 应用程序，我有一个 html 页面，我想在其上添加一个链接到此 Java 代码的按钮
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// listeners of our two buttons
View.OnClickListener handler = new View.OnClickListener() {
public void onClick(View v) {
switch (v.getId()) {
case R.id.buttonShareTextUrl:
shareTextUrl();
break;
}
}
};
// our buttons
findViewById(R.id.buttonShareTextUrl).setOnClickListener(handler);
}
// Method to share either text or URL.
private void shareTextUrl() {
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setType("text/plain");
share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
// Add data to the intent, the receiving app will decide
// what to do with it.
share.putExtra(Intent.EXTRA_SUBJECT, "book");
share.putExtra(Intent.EXTRA_TEXT, "https://play.google.com/store/apps/details?id=com.sohaibm.assrar_bac");
startActivity(Intent.createChooser(share, "share with"));
}
}
所以我希望您给我一个包含链接到此 Activity 的按钮的页面的 HTML 代码，非常感谢您
最佳答案
如果您使用 WebView 显示图书内容，您可以使用 WebViewClient:
WebViewClient mWebClient = new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.startsWith("handle:")){
// do something
return true;
}
else{
view.loadUrl(url);
}
return true;
}
};
mWebView.setWebViewClient(mWebClient);
您的链接应该是:
<a href="handle://it.to.me">Link text</a>
