我想添加一个带有按钮的新标签页。我没有遇到错误,但我的应用已在模拟器中停止。我的错误在哪里?谢谢您的全力帮助。注意:我的英语不好,抱歉。如果您没有关于主题的代码或想法,请不要编写pls。
private Button Add_Tab_Button;
int counter=0,counter2;
String[] Strings={
"Section "+counter,
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Add_Tab_Button=(Button) findViewById(R.id.Add_Tab_Button);
final String[] Strings2 = new String[Strings.length+1];
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
Add_Tab_Button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int array_size=Strings.length+1;
for(; counter <array_size ; counter++)
Strings2[counter] = Strings[counter];
counter2=counter+1;
Strings2[counter2]="Section "+counter2;
}
});
// Setup spinner
Spinner spinner = (Spinner) findViewById(R.id.spinner);
spinner.setAdapter(new MyAdapter(
toolbar.getContext(),
Strings2));
