Android Dialog万能适配器

一个BaseDialog就可以走遍整个APP，只需要编写XML布局就行。

public class BaseDialog extends Dialog {    private Context context;    public BaseDialog(Context context) {        super(context);        this.context = context;    }    public BaseDialog(Context context, int themeResId) {        super(context, themeResId);        this.context = context;    }    protected BaseDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {        super(context, cancelable, cancelListener);        this.context = context;    }    /*        显示对话框,参数：AppCompatActivity对象、Dialog对象、布局文件、背景资源文件、宽高比例         */    public void config(int layoutResID_contentView, int gravity, int anim, float width_config, float height_config, boolean canceledOnTouchOutside) {        requestWindowFeature(Window.FEATURE_NO_TITLE);// 去除对话框的标题        setContentView(layoutResID_contentView);//填充对话框布局        Window window = getWindow();        WindowManager.LayoutParams lp = window.getAttributes();        lp.dimAmount = 0.2f;        window.setBackgroundDrawableResource(R.drawable.dialog_bg);//设置对话框边框背景,必须在代码中设置对话框背景，不然对话框背景是黑色的        window.setGravity(gravity);        switch (anim) {            case 0://从底部进入                window.setWindowAnimations(R.style.dialog_anim_bottom);                break;            case 1://从头部进入                window.setWindowAnimations(R.style.dialog_anim_top);                break;            default:                window.setWindowAnimations(R.style.dialog_zoom);                break;        }        if (width_config != 0 && height_config != 0) {            window.setLayout((int) (ScreenUtils.getScreenWidth(context) * width_config), (int) (ScreenUtils.getScreenHeight(context) * height_config));        } else {            window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);        }        setCanceledOnTouchOutside(canceledOnTouchOutside ? true : false);    }    public void config(int layoutResID_contentView, int gravity, int anim, boolean canceledOnTouchOutside) {        requestWindowFeature(Window.FEATURE_NO_TITLE);// 去除对话框的标题        setContentView(layoutResID_contentView);//填充对话框布局        Window window = getWindow();        WindowManager.LayoutParams lp = window.getAttributes();        lp.dimAmount = 0.2f;        window.setBackgroundDrawableResource(R.drawable.dialog_bg);//设置对话框边框背景,必须在代码中设置对话框背景，不然对话框背景是黑色的        window.setGravity(gravity);        switch (anim) {            case 0://从底部进入                window.setWindowAnimations(R.style.dialog_anim_bottom);                break;            case 1://从头部进入                window.setWindowAnimations(R.style.dialog_anim_top);                break;            default:                window.setWindowAnimations(R.style.dialog_zoom);                break;        }        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);        setCanceledOnTouchOutside(canceledOnTouchOutside ? true : false);    }    public void setMarginTop(int top) {        Window window = getWindow();        WindowManager.LayoutParams layoutParams = window.getAttributes();        layoutParams.y = top;    }}
