自定义AlertDialog

自定义AlertDialog

先上效果图



这是我自定义的背景透明的,可全局使用的,有动画的AlertDialog

使用方法:

定义:loadingProgressDialog = new LoadingProgressDialog(this, “正在加载中…”, R.drawable.animation_loading);

显示:loadingProgressDialog.show();

隐藏:loadingProgressDialog.dismiss();

源码如下:

public class LoadingProgressDialog extends AlertDialog {
/**
* 动画的资源文件
*/
private int mResId;
/**
* 对话框的标题
*/
private String mLoadingTitle;
private Context mContext;
/**
* 显示图片
*/
private ImageView mImage;
/**
* 显示标题
*/
private TextView mContent;
/**
* 动画
*/
private AnimationDrawable mAnimation;

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

public LoadingProgressDialog(Context context, int theme) {
super(context, theme);
}

public LoadingProgressDialog(@NonNull Context context, boolean cancelable, @Nullable
OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
}

/**
* 构造方法
*
* @param context Context
* @param content 标题
* @param resId   动画资源
*/
public LoadingProgressDialog(Context context, String content, int resId) {
super(context,R.style.loadingDialog);
this.mContext = context;
this.mLoadingTitle = content;
this.mResId = resId;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

initView();
initData();
}

private void initView() {
setContentView(R.layout.layout_loading);
mImage = (ImageView) findViewById(R.id.iv_loading);
mContent = (TextView) findViewById(R.id.tv_loading);

//点击其他地方不能取消
setCanceledOnTouchOutside(false);

//设置对话框的宽度为屏幕宽度的一般
Window window = getWindow();
if (window != null) {
WindowManager.LayoutParams attributes = window.getAttributes();
attributes.width = DevicesUtil.getDeviceWidth(mContext).widthPixels / 2;
window.setAttributes(attributes);
}
}

private void initData() {
//设置图片的资源
mImage.setBackgroundResource(mResId);
//获取图片背景
mAnimation = (AnimationDrawable) mImage.getBackground();
mImage.post(new Runnable() {
@Override
public void run() {
mAnimation.start();
}
});
//设置标题
mContent.setText(mLoadingTitle);
}
}

自定义的步骤

设置布局

设置宽高

设置控件上的内容

设置图片的动画

附动画源码:

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/loading1"
android:duration="100"/>
<item android:drawable="@drawable/loading2"
android:duration="100"/>
<item android:drawable="@drawable/loading3"
android:duration="100"/>
<item android:drawable="@drawable/loading4"
android:duration="100"/>

</animation-list>
