本文实例为大家分享了Android实现单项、多项选择操作的相关代码,供大家参考,具体内容如下
1、单项选择
1.1.布局
1.2.Java文件
public class SingChoose extends AppCompatActivity {
private Button btn;
private RadioButton rbD;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sing_choose);
rbD= (RadioButton) this.findViewById(R.id.rb4);
btn= (Button) this.findViewById(R.id.submit);
btn.setonClickListener(new View.onClickListener() {
@Override
public void onClick(View v) {
if(rbD.isChecked()){
Toast.makeText(SingChoose.this,"正确,请加五分",Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(SingChoose.this,"错误,请减五分",Toast.LENGTH_SHORT).show();
}
}
});
}
}
效果图:
2、多项选择
2.1.布局
2.2.Java文件
public class CheckChoose extends AppCompatActivity implements CompoundButton.onCheckedChangeListener {
private CheckBox cb1,cb2,cb3,cb4,cb5;
private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.check_choose);
tv= (TextView) this.findViewById(R.id.tv);
cb1= (CheckBox) this.findViewById(R.id.cb1);
cb2= (CheckBox) this.findViewById(R.id.cb2);
cb3= (CheckBox) this.findViewById(R.id.cb3);
cb4= (CheckBox) this.findViewById(R.id.cb4);
cb5= (CheckBox) this.findViewById(R.id.cb5);
cb1.setonCheckedChangeListener(this);
cb2.setonCheckedChangeListener(this);
cb3.setonCheckedChangeListener(this);
cb4.setonCheckedChangeListener(this);
cb5.setonCheckedChangeListener(this);
}
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
String str="您喜欢:";
if(cb1.isChecked()){
str+=cb1.getText()+",";
}
if(cb2.isChecked()){
str+=cb2.getText()+",";
}
if(cb3.isChecked()){
str+=cb3.getText()+",";
}
if(cb4.isChecked()){
str+=cb4.getText()+",";
}
if(cb5.isChecked()){
str+=cb5.getText()+",";
}
tv.setText(str);
}
}
效果图:
