Android 自定義View一Dialog

之前的項目中很多地方都有用到形形色色的自定義View，之前一直都在忙，現在陸陸續續的把這些View整理出來
一：Dialog 因爲是電商項目 所以dialog也是比較多的
public class BaseDialog extends View{

public int type;//預留作用字段
protected Context mContext;
protected int layoutResId;
protected int gravity = Gravity.CENTER;
private Dialog dialog;
private SparseArray<View> mViews;
private DialogShowListener listener;


/**
 * 構造方法
 * @param context 上下文
 * @param layoutResId 佈局id
 */
public BaseDialog(Context context, int layoutResId, boolean cancelOnTouchOutside){
    super(context);
    this.mContext = context;
    mViews = new SparseArray<>();
    this.layoutResId = layoutResId;
    initView(cancelOnTouchOutside);

}

public BaseDialog(Context context) {
    super(context);
}


/**
 * 設置位置
 * @param gravity
 */
public void setGravity(int gravity){
    this.gravity = gravity;
    dialog.getWindow().setGravity(gravity);
}

/**
 * 初始化view
 */
private void initView(boolean cancelOnTouchOutside) {
    dialog = new Dialog(mContext);

    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
    WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
    dialog.setContentView(layoutResId);
    dialog.getWindow().setGravity(gravity);
    dialog.setCanceledOnTouchOutside(cancelOnTouchOutside);
   params.width = WindowManager.LayoutParams.MATCH_PARENT;
   params.height = WindowManager.LayoutParams.WRAP_CONTENT;
  dialog.getWindow().setAttributes(params);
     dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
            WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
     dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    cancelDialogTitleLineColor();
}
/**
 * 取消藍色線 4.4系統出現藍線
 */
private void cancelDialogTitleLineColor(){
    int divierId = mContext.getResources().getIdentifier("android:id/titleDivider", null, null);
    View divider = dialog.findViewById(divierId);
    if(divider != null){
        divider.setBackgroundColor(Color.WHITE);
    }
}

/**
 * 通過id尋找到控件
 * @param viewId
 * @param <T>
 * @return
 */
public <T extends View> T getView(int viewId) {
    View view = mViews.get(viewId);
    if (view == null) {
        view = dialog.findViewById(viewId);
        mViews.put(viewId, view);
    }
    return (T) view;
}

/**
 * 設置文本數據
 * @param viewId TextView 的 Id
 * @param textContent 文本內容
 * @return
 */
public BaseDialog setText(int viewId, String textContent){
    TextView textView = getView(viewId);
    textView.setText(textContent);
    return this;
}

/**
 * 設置文本數據
 * @param viewId TextView 的 Id
 * @param resId 文本內容資源id
 * @return
 */
public BaseDialog setText(int viewId, int resId){
    TextView textView = getView(viewId);
    textView.setText(resId);
    return this;
}



public void showDialog(){
    if(dialog!=null){
        dialog.show();
    }
}

public void dismissDialog(){
    if(dialog != null){
        dialog.dismiss();
    }
}

public Dialog getDialog(){
    return dialog;
}

/**
 * 切換dialog
 */
public void toggleDialog(){
    if(dialog != null){
        if(dialog.isShowing()){
            dialog.dismiss();
            if(listener != null){
                listener.onDismiss();
            }
        }else{
            dialog.show();
        }
    }
}

public void setDis(boolean dis) {
    if (dis) {
        dialog.setCancelable(false);
    } else {
        dialog.setCancelable(true);
    }
}


public boolean isShowing(){
    return dialog.isShowing();
}

/**
 * 監聽對話框的消失
 * @param listener
 */
public void setDialogShowListener(DialogShowListener listener){
    this.listener = listener;
}

public void setOnKeyDown(DialogInterface.OnKeyListener listener){
    dialog.setOnKeyListener(listener);
}

public interface DialogShowListener {
    void onDismiss();
}
