在我的应用程序中,我目前使用Web视图显示一些内容,然后使用Javascript注入快速填写用户的表单.唯一的问题是,与Chrome自定义标签相比,Webview的速度非常慢.是否可以将Javascript代码注入这些自定义选项卡？

例如,以下是我目前使用的一些代码:

myWebView.loadUrl("javascript:document.getElementById('join_first_name').value='" + name + "';void(0); ");

在这里,我有一个代码块,可以将当前活动的信息发送到另一个活动:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tutorial);

        prefs = getSharedPreferences("com.amrapps.paneraautomate", MODE_PRIVATE);

        name = (EditText) findViewById(R.id.name);
        lastName = (EditText) findViewById(R.id.lastName);
        password = (EditText) findViewById(R.id.password);
        final CheckBox passwordReveal = (CheckBox) findViewById
                (R.id.checkbox);

        passwordReveal.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
                } else {
                    password.setInputType(129);
                }
            }
        });
    }

    public void continueButton(View v) {
        String stringName = name.getText().toString();
        String stringLastName = lastName.getText().toString();
        String stringPassword = password.getText().toString();

        SharedPreferences.Editor editor = prefs.edit();
        prefs.edit().putString("name", stringName).commit();
        prefs.edit().putString("lastName", stringLastName).commit(); …

我试图得到所有偶数斐波纳契数的总和.我可以打印出数字,但我无法得到它们的总和.这是在java中.

class driver {
    public static void main(String [] args) {
        int a; 
        int b = 0;
        int c = 1;

        for (int i = 0; i < 10; i++) { // Finds fibonacci sequence
            a = b;
            b = c;
            c = a + b;

            if ( c % 2 == 0) { // Check if it's even
                int sum = 0;
                sum = sum + c;
                System.out.println(sum);
            }
            else {

            }
        }
    }
}
