最近项目里面用到了一个地址选择器,实现现在主流的WheelView滑动选择,整理了下,做了个Demo.废话不多说,直接上代码:
主布局:
MainActivity:
package com.example.user.myapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
private TextView select_address_tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
select_address_tv= (TextView) findViewById(R.id.select_address_tv);
select_address_tv .setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ChangeAddressPopwindow mChangeAddressPopwindow = new ChangeAddressPopwindow(MainActivity.this);
mChangeAddressPopwindow.setAddress("广东", "深圳", "福田区");
mChangeAddressPopwindow.showAtLocation(select_address_tv, Gravity.BOTTOM, 0, 0);
mChangeAddressPopwindow
.setAddresskListener(new ChangeAddressPopwindow.OnAddressCListener() {
@Override
public void onClick(String province, String city, String area) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this,
province + "-" + city + "-" + area,
Toast.LENGTH_LONG).show();
select_address_tv.setText(province + city + area);
}
});
}
});
}
}
