android 自定义 dialog

 

1. 继承Dialog类

import android.animation.ObjectAnimator;
import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.animation.LinearInterpolator;
import android.widget.ImageView;
import android.widget.TextView;
import com.xxx.xxx.R;
import com.xxx.xxx.interfaces.ILoadingListening;

public class XXXLoadingDialog extends Dialog implements ILoadingListening {
    private Context context;
    private ImageView progress;

    public LoadingDialog(Context context, String msg) {
        super(context, R.style.no_title);
        this.context = context;
        initView(msg);
    }

    private void initView(String msg) {
        View dialogView = LayoutInflater.from(context).inflate(R.layout.XXXloading, null);
        setContentView(dialogView);
        setCanceledOnTouchOutside(false);
        setCancelable(true);

        progress = dialogView.findViewById(R.id.progress);
        TextView title = dialogView.findViewById(R.id.title);
        if (msg != null && msg.length() > 0) {
            title.setText(msg);
        }
    }

    @Override
    public void show() {
        super.show();
        ObjectAnimator rotation = ObjectAnimator.ofFloat(progress, "rotation", 0f, 359f);
        rotation.setRepeatCount(ObjectAnimator.INFINITE);
        rotation.setInterpolator(new LinearInterpolator());
        rotation.setDuration(1000);
        rotation.start();
    }

    @Override
    public void setIsCancelLoading(boolean iscancel) {
        setCancelable(iscancel);
    }

    @Override
    public void showLoading() {
        show();
    }

    @Override
    public void hiedLoading() {
        if (isShowing()) {
            dismiss();
        }
    }
}

　　2. dialog布局

　　

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_gravity="center"
        android:layout_margin="40dp"
        android:gravity="center"
        android:orientation="vertical"
        android:paddingBottom="20dp"
        android:paddingTop="20dp"
        android:visibility="visible">

        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:gravity="center">

            <ImageView
                android:id="@+id/progress"
                android:layout_width="150dp"
                android:layout_height="150dp"
                android:background="@mipmap/loading" />
        </RelativeLayout>

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:gravity="center"
            android:text="加载中"
            android:textColor="@color/gray"
            android:textSize="40sp" />
    </LinearLayout>
</RelativeLayout>

　　3. 使用

　　全局变量定义

private XXXDialog loading;

　　初始化

loading = new XXXDialog(this, getString(R.string.loading));

　　显示调用

loading.showLoading();

　　隐藏调用

loading.hiedLoading();
