SearchView to Edittext search
问题
我是Android初学者，我有一个搜索MySQL数据库并使用JSON显示结果的代码。我的问题是，我想将SearchView更改为EditText（id）和Button（searchbtn）。当点击搜索按钮时，它应该给我结果。我该如何更改它？以下是您的代码部分：
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String query) {
// 在这里添加处理EditText和Button的代码
// 当点击按钮时，执行搜索操作并显示结果
// 你需要使用query作为搜索关键字
// 之后，你可以调用searchSpacecraft方法来执行搜索
// 最后，将结果传递给populateListView方法来显示结果
return false;
}
});
请注意，你需要在onQueryTextChange方法中添加处理EditText和Button的代码，以便在点击按钮时执行搜索操作并显示结果。你可以使用query作为搜索关键字，调用searchSpacecraft方法来执行搜索，然后将结果传递给populateListView方法来显示结果。

@Override
public boolean onQueryTextChange(String query) {
final Call<List<Spacecraft>> call = myAPIService.searchSpacecraft(query);
call.enqueue(new Callback<List<Spacecraft>>() {
@Override
public void onResponse(Call<List<Spacecraft>> call, Response<List<Spacecraft>> response) {
mProgressBar.setVisibility(View.GONE);
populateListView(response.body());
}
@Override
public void onFailure(Call<List<Spacecraft>> call, Throwable throwable) {
populateListView(new ArrayList<Spacecraft>());
mProgressBar.setVisibility(View.GONE);
Toast.makeText(MainActivity.this, "ERROR: "+throwable.getMessage(), Toast.LENGTH_LONG).show();

只需通过yourEditText.getText()从EditText中获取文本，然后将该值传递给您的请求...所有这些都在onButtonClickListener中进行。
以下是代码部分：
searchBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// 从编辑框中获取值
String result = yourEdittext.getText().toString();
// 然后将值传递给您的请求，如下所示
final Call<List<Spacecraft>> call = myAPIService.searchSpacecraft(result);
call.enqueue(new Callback<List<Spacecraft>>() {
@Override
public void onResponse(Call<List<Spacecraft>> call, Response<List<Spacecraft>> response) {
mProgressBar.setVisibility(View.GONE);
populateListView(response.body());
}
@Override
public void onFailure(Call<List<Spacecraft>> call, Throwable throwable) {
populateListView(new ArrayList<Spacecraft>());
mProgressBar.setVisibility(View.GONE);
Toast.makeText(MainActivity.this, "ERROR: " + throwable.getMessage(), Toast.LENGTH_LONG).show();
}
});
}
});
英文:
Just get the text from your editText by yourEditText.getText(); and pass the value to your request .. all this in the onButtonClickListener
follow belwo code
searchBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Get the value from edit text
String result = yourEdittext.getText().toString();
//Then pass the value to your request like that
final Call<List<Spacecraft>> call = myAPIService.searchSpacecraft(result);
call.enqueue(new Callback<List<Spacecraft>>() {
@Override
public void onResponse(Call<List<Spacecraft>> call, Response<List<Spacecraft>> response) {
mProgressBar.setVisibility(View.GONE);
populateListView(response.body());
}
@Override
public void onFailure(Call<List<Spacecraft>> call, Throwable throwable) {
populateListView(new ArrayList<Spacecraft>());
mProgressBar.setVisibility(View.GONE);
Toast.makeText(MainActivity.this, "ERROR: "+throwable.getMessage(), Toast.LENGTH_LONG).show();
}
});
}
});
