我有動態加載視圖的問題。當我從Spinner中選擇第一個項目時，我有三個動態微調視圖，它應該在第二個微調控件上方創建一個文本視圖，但它在第三個微調控件下面創建一個視圖。任何人都可以指導我如何實現它。我已經在下面分享了我的代碼。使用微調創建動態視圖在Android中可靠可靠
/add LayoutParams
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
rl.setOrientation(LinearLayout.VERTICAL);
// add spinner
String[] spinnerArray = {"Android","ios","other"};
Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerArray); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter);
String[] spinnerArray1 = {"flowers","vegetables","other"};
Spinner spinner1 = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerArray1); //selected item will look like a spinner set from XML
spinnerArrayAdapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(spinnerArrayAdapter1);
String[] spinnerArray2 = {"cat","dog","other"};
Spinner spinner2 = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, spinnerArray2); //selected item will look like a spinner set from XML
spinnerArrayAdapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner2.setAdapter(spinnerArrayAdapter2);
rl.addView(spinner);
rl.addView(spinner1);
rl.addView(spinner2);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
if(position==1)
{
TextView tv = new TextView(MainActivity.this);
tv.setText("Hello");
rl.addView(tv);
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
