如果我发布了一个警告框,我想阻止TouchEvent,实际上我可以按下屏幕,我可以访问受密码保护的屏幕。然后如何保护对屏幕的访问,就像我的密码是真的一样。我的对话框由以下代码给出:

void showDialog() {
        final String myPassword = getResources().getString(R.string.password);

        AlertDialog.Builder alert = new AlertDialog.Builder(this);
        alert.setTitle(R.string.connection);
        // Set an EditText view to get user input
        final EditText input = new EditText(this);
        input.setInputType(InputType.TYPE_CLASS_TEXT
                | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        alert.setView(input);

        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                String value = input.getText().toString();
                String hashedPassword = Utilities.md5(value);
                if (myPassword.equalsIgnoreCase(hashedPassword)) {
                    //code
                } else {
                    Toast.makeText(getApplicationContext(),
                            "Mot de passe incorrect", Toast.LENGTH_LONG).show();
                    admin = false;
                    Intent intent = getIntent();
                    finish();
                    startActivity(intent);
                }
            }
        });
        alert.setNegativeButton("Annuler",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        // Canceled.
                        Intent intent = getIntent();
                        finish();
                        startActivity(intent);
                    }
                });
        alert.show();
    }

我不确定我是否理解,但试试这个:

alert.setCancelable(false);
