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
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

package com.example.hfs.alipayuidemo;import android.app.Dialog;import android.os.Bundle;import android.support.annotation.NonNull;import android.support.v4.app.DialogFragment;import android.view.Gravity;import android.view.View;import android.view.Window;import android.view.WindowManager;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.widget.Button;import android.widget.EditText;import android.widget.LinearLayout;import android.widget.ListView;import android.widget.RelativeLayout;/** * 底部弹窗Fragment */public class PayDetailFragment extends DialogFragment { private RelativeLayout rePayWay, rePayDetail, reBalance; private LinearLayout LinPayWay,linPass; private ListView lv; private Button btnPay; private EditText gridPasswordView; @NonNull @Override public Dialog onCreateDialog(Bundle savedInstanceState) { // 使用不带Theme的构造器, 获得的dialog边框距离屏幕仍有几毫米的缝隙。 Dialog dialog = new Dialog(getActivity(), R.style.BottomDialog); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); // 设置Content前设定 dialog.setContentView(R.layout.fragment_pay_detail); dialog.setCanceledOnTouchOutside(true); // 外部点击取消 // 设置宽度为屏宽, 靠近屏幕底部。 final Window window = dialog.getWindow(); window.setWindowAnimations(R.style.AnimBottom); final WindowManager.LayoutParams lp = window.getAttributes(); lp.gravity = Gravity.BOTTOM; // 紧贴底部 lp.width = WindowManager.LayoutParams.MATCH_PARENT; // 宽度持平 lp.height = getActivity().getWindowManager().getDefaultDisplay().getHeight() * 3 / 5; window.setAttributes(lp); rePayWay = (RelativeLayout) dialog.findViewById(R.id.re_pay_way); rePayDetail = (RelativeLayout) dialog.findViewById(R.id.re_pay_detail);//付款详情 LinPayWay = (LinearLayout) dialog.findViewById(R.id.lin_pay_way);//付款方式 lv = (ListView) dialog.findViewById(R.id.lv_bank);//付款方式(银行卡列表) reBalance = (RelativeLayout) dialog.findViewById(R.id.re_balance);//付款方式(余额) btnPay = (Button) dialog.findViewById(R.id.btn_confirm_pay); gridPasswordView = (EditText) dialog.findViewById(R.id.pass_view); linPass = (LinearLayout)dialog.findViewById(R.id.lin_pass); rePayWay.setOnClickListener(listener); reBalance.setOnClickListener(listener); btnPay.setOnClickListener(listener); return dialog; } View.OnClickListener listener = new View.OnClickListener() { @Override public void onClick(View view) { Animation slide_left_to_left = AnimationUtils.loadAnimation(getActivity(), R.anim.slide_left_to_left); Animation slide_right_to_left = AnimationUtils.loadAnimation(getActivity(), R.anim.slide_right_to_left); Animation slide_left_to_right = AnimationUtils.loadAnimation(getActivity(), R.anim.slide_left_to_right); Animation slide_left_to_left_in = AnimationUtils.loadAnimation(getActivity(), R.anim.slide_left_to_left_in); switch (view.getId()) { case R.id.re_pay_way: rePayDetail.startAnimation(slide_left_to_left); rePayDetail.setVisibility(View.GONE); LinPayWay.startAnimation(slide_right_to_left); LinPayWay.setVisibility(View.VISIBLE); break; case R.id.re_balance: rePayDetail.startAnimation(slide_left_to_left_in); rePayDetail.setVisibility(View.VISIBLE); LinPayWay.startAnimation(slide_left_to_right); LinPayWay.setVisibility(View.GONE); break; case R.id.btn_confirm_pay: rePayDetail.startAnimation(slide_left_to_left); rePayDetail.setVisibility(View.GONE); linPass.startAnimation(slide_right_to_left); 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); }}
