最快速的地区选择器

一、Android Studio中配置
dependencies {
compile 'com.chenenyu.areapicker:lib:1.0.1'
}

二、看案例

public class MainActivity extends AppCompatActivity implements AreaPicker.OnAreaPickListener {
private AreaPicker picker;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showAreaPicker();
        }
    });
}

private void showAreaPicker() {
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    Fragment prev = getSupportFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);
    picker = new AreaPicker();
    // 支持单级/省市/省市区联动
    //picker.setLevel(PickLevel.PROVINCE_CITY);
    ft.setCustomAnimations(R.anim.push_bottom_in, R.anim.push_bottom_out, R.anim.push_bottom_in, R.anim.push_bottom_out);
    picker.show(ft, "dialog");
}

@Override
public void onAreaPick(final String[] area) {
    Toast.makeText(this, area[0] + area[1] + area[2], Toast.LENGTH_SHORT).show();
}

}
