當我輸入「AA」到我的2 TextViews它永遠不會移動到我的其他acitivty時,「AA」.length()應該是2使它切換到我的其他活動但它從來沒有。然後我檢查了看它打印出來的結果是什麼,它應該是2 2的任何建議,打印98和94作爲2個字符串的長度?str.length()不工作,因爲我認爲它應該
public class DataEntry extends Activity {
String parent1 = "";
String parent2 = "";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_data_entry);
Button calc = (Button)findViewById(R.id.btnCalc);
calc.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
TextView tv = (TextView)findViewById(R.id.txtFirstParent);
TextView tv1 = (TextView)findViewById(R.id.txtParent2);
String str = tv.toString().trim();
String str2 = tv1.toString().trim();
parent1 = str;
parent2 = str2;
if(str.length()==2 && str2.length()==2){
Intent otherIntent = new Intent(DataEntry.this, MonoHybrid.class);
otherIntent.putExtra("parent1",parent1);
otherIntent.putExtra("parent2",parent2);
startActivity(otherIntent);
}
else if(str.length()==4 && str2.length()==4){
Intent otherIntent = new Intent(DataEntry.this, DiHybrid.class);
otherIntent.putExtra("parent1",parent1);
otherIntent.putExtra("parent2",parent2);
startActivity(otherIntent);
}
else if(str.length()==6 && str2.length()==6){
Intent otherIntent = new Intent(DataEntry.this, TriHybrid.class);
otherIntent.putExtra("parent1",parent1);
otherIntent.putExtra("parent2",parent2);
startActivity(otherIntent);
}
else
tv.setText(str.length() +" "+ str2.length());
tv1.setText(str.length() + " " + str2.length());
//tv.setText("Error please enter a MonoHybrid \"AA\" DiHybrid \"AABB\" or TriHybrid \"AABBCC\"");
//tv1.setText("Error please enter a MonoHybrid \"AA\" DiHybrid \"AABB\" or TriHybrid \"AABBCC\"");
}
});
}
}
