一自定义Dialog

/** * 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);    }}

二 dialog布局layount loadingdialog.xml

<?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...");    }}

这样就简单实现了
