android 自定义实现圆角Dialog

首先我们需要自定义dialog布局文件view_input_pwd_dialog.xml，如下：

<?xml version="1.0" encoding="utf-8"?>

dialog背景圆角定义dialog_bg.xml：

<?xml version="1.0" encoding="UTF-8"?>

代码实现：

  LayoutInflater inflater = LayoutInflater                .from(getActivity());        LinearLayout layout = (LinearLayout) inflater.inflate(                R.layout.view_input_pwd_dialog, null);        final EditTextWithLabel pwdEt = (EditTextWithLabel) layout                .findViewById(R.id.edit_text);        Button firmBtn = (Button) layout                .findViewById(R.id.btn_dialog_firm);        Button cancleBtn = (Button) layout                .findViewById(R.id.btn_dialog_give_up);        TextView wifiNameTv = (TextView) layout.findViewById(R.id.wifi_name);        wifiNameTv.setText(getString(R.string.share_wifi_name_lable, wifi.hot_name));        pwdEt.getEditText().setInputType(InputType.TYPE_CLASS_TEXT                | InputType.TYPE_TEXT_VARIATION_PASSWORD);        pwdEt.getImageView().setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                EditText editText = pwdEt.getEditText();                int hide = InputType.TYPE_CLASS_TEXT                        | InputType.TYPE_TEXT_VARIATION_PASSWORD;                int show = InputType.TYPE_CLASS_TEXT                        | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD;                if (editText.getInputType() == hide) {                    editText.setInputType(show);                    pwdEt.getImageView().setImageResource(R.mipmap.pwd_show);                } else {                    editText.setInputType(hide);                    pwdEt.getImageView().setImageResource(R.mipmap.pwd_hide);                }                pwdEt.getEditText().setSelection(pwdEt.getText().toString().length());            }        });        final AlertDialog dlg = new AlertDialog.Builder(                getActivity()).create();        dlg.setView(layout, 0, 0, 0, 0);//防止黑边        dlg.setCancelable(true);        firmBtn.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                String pwd = pwdEt.getText().toString();                if (StringUtils.isEmpty(pwd)) {                    ToastUtils.show("密码不能为空，请确认");                    return;                }                if (!StringUtils.isEmpty(pwd) && pwd.length() < 8) {                    ToastUtils.show("密码位数不正确，请确认");                    return;                }                wifi.password = pwd;                mNetId = mHotManager.connectWiFi(wifi);                mFragmentHomeBinding.header.setCenterText(wifi.hot_name, 20);                updateConnectingUI(getResources().getString(R.string.be_connecting));                isConnecting = true;                mFragmentHomeBinding.header.startAnimation();                dlg.dismiss();            }        });        cancleBtn.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                dlg.dismiss();            }        });        Window window = dlg.getWindow();        window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));  // 有白色背景，加这句代码        dlg.show();        //获取屏幕的长宽        WindowManager windowManager = getActivity().getWindowManager();        Display display = windowManager.getDefaultDisplay();        int screenheight = display.getHeight();        int screenWidth = display.getWidth();        //设置弹出框的长宽        dlg.getWindow().setLayout(screenWidth * 4 / 5, screenheight * 2 / 5);
