android-實現支付寶支付從底部彈窗效果
前言
我們再用支付寶支付的時候,會從底部彈上來一個對話方塊,讓我們選擇支付方式等等,今天我們就來慢慢實現這個功能
效果圖
實現
主介面很簡單,就是一個按鈕,點選後跳到支付詳情的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");
}
});
}
}
