推荐答案
不用担心小失误
改变这一行
mybrowser.addJavascriptInterface(new MyjavaScriptInterface(), "AndroidFUNCTION");
要
mybrowser.addJavascriptInterface(new MyjavaScriptInterface(), "AndroidFunction");
更新：
您 JavascriptInterface 想这个
UPDATE:
Your JavascriptInterface Should like this
public class MyjavaScriptInterface{
MyjavaScriptInterface() {
}
@JavascriptInterface
public void openAndroidDialog(){
AlertDialog.Builder myDialog
= new AlertDialog.Builder(MainActivity.this);
myDialog.setTitle("DANGER!");
myDialog.setMessage("You can do what you want!");
myDialog.setPositiveButton("ON", null);
myDialog.show();
}
}
OUTPUT：
如何打开watsapp？
Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.setType("text/plain");
String text = "YOUR TEXT HERE";
waIntent.setPackage("com.whatsapp");
if (waIntent != null) {
waIntent.putExtra(Intent.EXTRA_TEXT, text);//
startActivity(Intent.createChooser(waIntent, "Share with"));
} else {
Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
.show();
}
