Android自定义进度条

核心代码：

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            //动画进度条
            case R.id.anim:
                //显示动画进度条
                showRoundProcessDialog(this, R.layout.loading_process_dialog_anim);
                break;
            //颜色进度条
            case R.id.color:
                //显示颜色进度条
                showRoundProcessDialog(this, R.layout.loading_process_dialog_color);
                break;
            //图片进度条
            case R.id.icon:
                //显示图片进度条
                showRoundProcessDialog(this, R.layout.loading_process_dialog_icon);
                break;
            default:
                break;
        }
    }

    public void showRoundProcessDialog(Context mContext, int layout) {
        //初始化进度条
        mDialog = new AlertDialog.Builder(mContext).create();
        //显示进度条
        mDialog.show();
        // 注意此处要放在show之后 否则会报异常
        mDialog.setContentView(layout);
        // mDialog.setCancelable(false); //false设置点击其他地方不能取消进度条
    }
