我们再用支付宝支付的时候,会从底部弹上来一个对话框,让我们选择支付方式等等,今天我们就来慢慢实现这个功能

效果图

Android仿支付宝支付从底部弹窗效果

实现

主界面很简单,就是一个按钮,点击后跳到支付详情的Fragment中

package com.example.hfs.alipayuidemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

 private Button mButton;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  initView();
 }

 private void initView() {
  mButton= (Button) this.findViewById(R.id.btn_pay);
  mButton.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {

    PayDetailFragment payDetailFragment=new PayDetailFragment();
    payDetailFragment.show(getSupportFragmentManager(),"payDetailFragment");
   }
  });
 }
}

接着是支付详情的Fragment代码

<?xml version="1.0" encoding="utf-8"?>

 android:layout_width="match_parent"

     linPass.setVisibility(View.VISIBLE);
     break;
    default:
     break;
   }
  }
 };
}

还有一个ScrollView嵌套ListView的问题,主要是重写ListView的计算高度

package com.example.hfs.alipayuidemo;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;

/**
 * ScrollView中嵌套ListView,重写ListView计算高度
 */
public class ScrollviewListView extends ListView {
 public ScrollviewListView(Context context) {
  super(context);
 }

 public ScrollviewListView(Context context, AttributeSet attrs) {
  super(context, attrs);
 }

 public ScrollviewListView(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
 }

 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

  int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,

    MeasureSpec.AT_MOST);

  super.onMeasure(widthMeasureSpec, expandSpec);

 }
}

好了,其实还是挺好理解的,附上GitHub项目地址: https://github.com/Greathfs/AliPayUiDemo
