Android-使用代码创建AutoCompleteTextView（完全没有xml）
- 先创建AutoCompleteTextView的实例：
AutoCompleteTextView autoCompleteTextView = new AutoCompleteTextView(context);
- 设置AutoCompleteTextView的布局参数：
autoCompleteTextView.setLayoutParams(new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
- 给AutoCompleteTextView设置适配器，这里使用了一个简单的字符串数组适配器：
String[] suggestions = {"Apple", "Banana", "Cherry", "Coconut"}; ArrayAdapter adapter = new ArrayAdapter(context, android.R.layout.simple_dropdown_item_1line, suggestions); autoCompleteTextView.setAdapter(adapter);
- 最后将AutoCompleteTextView添加到父布局中：
parentLayout.addView(autoCompleteTextView);
完整示例代码：
LinearLayout parentLayout = findViewById(R.id.parent_layout);
AutoCompleteTextView autoCompleteTextView = new AutoCompleteTextView(context); autoCompleteTextView.setLayoutParams(new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
String[] suggestions = {"Apple", "Banana", "Cherry", "Coconut"}; ArrayAdapter adapter = new ArrayAdapter(context, android.R.layout.simple_dropdown_item_1line, suggestions); autoCompleteTextView.setAdapter(adapter);
parentLayout.addView(autoCompleteTextView);
