【问题描述】:
这是一个快速的问题。在我的应用程序中,用户经历了多个活动,这些活动为他们提供了可供选择的单选按钮......在最后的活动中,根据那里的选项,将显示他们是哪个角色等等......现在问题是我不知道'不知道如何编写代码才能做到这一点。这是我所拥有的
第一个活动
public class Quiz1 extends Activity {
Button btn;
RadioGroup rg1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.quiz1);
btn = (Button) findViewById(R.id.nextBtn1);
rg1= (RadioGroup) findViewById(R.id.rg1);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (rg1.getCheckedRadioButtonId() == -1) {
Toast.makeText(getApplicationContext(), "Please select an answer",
Toast.LENGTH_SHORT).show();
} else{
Intent intent = new Intent(getApplicationContext(), Quiz2.class);
Bundle bundle = getIntent().getExtras();
int id = rg1.getCheckedRadioButtonId();
RadioButton radioButton = (RadioButton) findViewById(id);
bundle.putString("rg1", radioButton.getText().toString());
intent.putExtras(bundle);
startActivity(intent);
}
}
});
}
}
第二次活动
Button btn;
RadioGroup rg2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.quiz2);
btn = (Button) findViewById(R.id.nextBtn2);
rg2= (RadioGroup) findViewById(R.id.rg2);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (rg2.getCheckedRadioButtonId() == -1) {
Toast.makeText(getApplicationContext(), "Please select an answer",
Toast.LENGTH_SHORT).show();
} else{
Intent intent = new Intent(getApplicationContext(), Quiz3.class);
Bundle bundle = getIntent().getExtras();
int id = rg2.getCheckedRadioButtonId();
RadioButton radioButton = (RadioButton) findViewById(id);
bundle.putString("rg2", radioButton.getText().toString());
intent.putExtras(bundle);
startActivity(intent);
}
}
});
}
}
这持续了大约 7 个活动
最终活动(显示结果和角色)
public class Final1 extends Activity {
Button btnRestart;
Button btnShare;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.final1);
Bundle bundle = getIntent().getExtras();
TextView textView = (TextView)findViewById(R.id.txt);
textView.setText(bundle.getCharSequence("rg"));
TextView textView1 = (TextView)findViewById(R.id.txt1);
textView1.setText(bundle.getCharSequence("rg1"));
TextView textView2 = (TextView)findViewById(R.id.txt2);
textView2.setText(bundle.getCharSequence("rg2"));
TextView textView3 = (TextView)findViewById(R.id.txt3);
textView3.setText(bundle.getCharSequence("rg3"));
TextView textView4 = (TextView)findViewById(R.id.txt4);
textView4.setText(bundle.getCharSequence("rg4"));
TextView textView5 = (TextView)findViewById(R.id.txt5);
textView5.setText(bundle.getCharSequence("rg5"));
TextView textView6 = (TextView)findViewById(R.id.txt6);
textView6.setText(bundle.getCharSequence("rg6"));
btnRestart = (Button)findViewById(R.id.restartBtn);
btnRestart.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent in = new Intent(v.getContext(), Quiz.class);
startActivityForResult(in, 0);
}
});
btnShare = (Button)findViewById(R.id.btnShare);
btnShare.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "check out this app";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));
}
});
}
}
现在,在最后的活动中,我想要一个代码,例如:
如果在 activity1(Quiz1) 中选择了 1 或 2 选项(如在选择的单选按钮中),
测验 2:选项 2 或 4
测验 3:选项 1 或 4
测验 2:选项 2 或 3
等等……
然后将文本视图更改为特定的内容,例如“你的角色是 x”
我已经把所有的信息带到了最后一堂课,我只是不知道如何解决这个问题,尽管听起来很简单。
任何帮助将不胜感激,谢谢
编辑:
TextView textviewResult = (TextView) findViewById(R.id.textViewResult);
if(bundle.getString("rg").equals("A")||(bundle.getString("rg").equals("B")&& bundle.getString("rg1").equals("B")&& bundle.getString("rg2").equals("Long range weapons")
&& bundle.getString("rg3").equals("C") || bundle.getString("rg3").equals("D") && bundle.getString("rg4").equals("A")||bundle.getString("rg4").equals("B")
|| bundle.getString("rg4").equals("CC") && bundle.getString("rg5").equals("A") || bundle.getString("rg5").equals("E")
&& bundle.getString("rg6").equals("Yes"))) {
textviewResult.setText("x");
}else{
textviewResult.setText("not x");
}
这个问题是,即使我为 rg 选择了另一个选项(所以不是“A”或“B”选项),但是对于其余部分,我选择了 If 语句中的选项,它仍然会说x(但应该说不是 x)
