代碼實作自定義dialog樣式

寫了一個函數，實作調用自定義的dialog，監聽的點選事件，可以适當加入，這裡實作針對ok的點選處理，主要傳入自定義的view的布局和寬高。

private void showTipDialog(Context context, int resId, int widthDp, int heightDp) {
        View view = LayoutInflater.from(context).inflate(resId, null);
        final Dialog dialog = new Dialog(context, R.style.dialog);
        dialog.setContentView(view);

        TextView sure = (TextView) view.findViewById(R.id.sure);
        sure.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
                finish();
            }
        });

        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);
        dialog.show();

        if (dialog.getWindow() != null) {
            WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
            params.width = (int) (widthDp * (this.getResources().getDisplayMetrics().density + 0.5f));
            params.height = (int) (heightDp * (this.getResources().getDisplayMetrics().density + 0.5f));
            dialog.getWindow().setAttributes(params);
        }

    }
           

然後在values中的styles.xml中加入：

<style name="dialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:backgroundDimAmount">0.6</item>
    </style>
