自定义 Dialog方式的加载动画

/**
* 自定义    加载动画Dialog
* Created by Administrator on 2016/9/1.
*/
public class MyLoadingDialog extends AlertDialog {
private int resBigLoading = R.mipmap.ic_loading;//要被做为  动画的图片
private RotateAnimation mRotateAnimation;
private ImageView ivBigLoading;
private TextView title;

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

public MyLoadingDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
super(context, cancelable, cancelListener);
}

public MyLoadingDialog(Context context, int themeResId) {
super(context, themeResId);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View view=LayoutInflater.from(getContext()).inflate(R.layout.loadingdialog, null, true);
setContentView(view);
init();
initViews();
setDialogSize(350,350);
}

/**
* 初始化
*/
private void initViews() {
ivBigLoading = (ImageView) findViewById(R.id.loadingdialog_ivBigLoading);
title=(TextView)findViewById(R.id.loadingdialog_tv);
//设置图片
ivBigLoading.setImageResource(resBigLoading);
//将图片动画
ivBigLoading.startAnimation(mRotateAnimation);
}

/**
* 初始化动画方法
*/
private void init() {
mRotateAnimation = new RotateAnimation(0f, 359f,
Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
mRotateAnimation.setDuration(1000L);
mRotateAnimation.setInterpolator(new LinearInterpolator());
mRotateAnimation.setRepeatCount(-1);
mRotateAnimation.setRepeatMode(Animation.RESTART);
}

/**
* 设置   dialog宽和高
* @param width
* @param height
*/
private void setDialogSize(int width, int height) {
WindowManager.LayoutParams params = getWindow().getAttributes();
params.width = width;
params.height = height;
this.getWindow().setAttributes(params);
}

/**
* 设置动画的标题
* @param str
*/
public void setTitle(String str){
title.setText(str);
}

}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp"
android:background="@drawable/loadingdialog_bg"
android:orientation="vertical">

<ImageView
android:id="@+id/loadingdialog_ivBigLoading"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center_horizontal"
android:src="@mipmap/ic_loading"
android:padding="8dp" />
<TextView
android:id="@+id/loadingdialog_tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text=""
android:textSize="10sp"
android:gravity="center"
/>
</LinearLayout>

三   loadingdialog_bg.xml文件

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/white"
></solid>
<!--圆角白色背景-->
<corners android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp">

</corners>
</shape>

</pre>

四   自定义好之后的就可以在activity里面用了

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void jiazaizhong(View view){
//加载dialog动画
MyLoadingDialog myLoadingDialog=new MyLoadingDialog(this);
myLoadingDialog.show();
//设置标题内容
myLoadingDialog.setTitle("加载中...");
}

public void shangchuanzhong(View view){
MyLoadingDialog myLoadingDialog=new MyLoadingDialog(this);
myLoadingDialog.show();
myLoadingDialog.setTitle("上传中...");
}
}
