本文介绍最常用的四种对话框的使用方法，包括普通（包含提示消息和按钮）对话框、列表展示对话框、加载对话框、编辑对话框等多种形式。
一、前期准备1. 设置对话框背景 dialog_bg_normal.xml
2. 设置风格
@drawable/dialog_bg_normal
@android:style/Animation.Dialog
@null
true
true
true
true
3. 自定义对话框

public class CommonDialog extends Dialog {
private Window mWindow;
public CommonDialog(@NonNull Context context) {
super(context);
}
public CommonDialog(@NonNull Context context, int themeResId) {
super(context, themeResId);
}
protected CommonDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
}
public void setView(View view) {
setContentView(view);
}
public void setView(int ID) {
setContentView(ID);
}
public void setProperty(int x,int y,int w,int h) {
mWindow = getWindow();
WindowManager.LayoutParams params = mWindow.getAttributes();
params.x = x; //设置对话框的位置，0为中间
params.y = y;
params.width = w;
params.height = h;
params.alpha = 1.0f; //设置对话框的透明度,1f不透明
params.gravity = Gravity.CENTER; //设置显示在中间
mWindow.setAttributes(params);
}
}
1. 效果图 
2. 布局文件 dialog_device_add_notice.xml
3. 逻辑代码
private CommonDialog mDialog;
public void click(View view) {
showDialog();
}
private void showDialog() {
mDialog = new CommonDialog(this,R.style.customDialog);
View view = View.inflate(this, R.layout.dialog_device_add_notice,null);
final LinearLayout llBefore = (LinearLayout)view.findViewById(R.id.ll_before);
final LinearLayout llAfter = (LinearLayout)view.findViewById(R.id.ll_after);
final ImageView imgWaiting = (ImageView) view.findViewById(R.id.img_config_icon1);
TextView txtTitle = (TextView) view.findViewById(R.id.txt_title);
txtTitle.setText(getString(R.string.base_update_notice));
final TextView txtMsg = (TextView) view.findViewById(R.id.txt_msg);
TextView txtCancle = (TextView) view.findViewById(R.id.txt_cancle);

}
}
});
mDialog.setView(view);
mDialog.setProperty(0,0,800,600);
mDialog.setCanceledOnTouchOutside(true);
mDialog.show();
}
1. 布局文件 dialog_delete_edit.xml
2. 逻辑代码
public void show2(View view) {
show();
}
private void show(){
