我想EditText暂时不关注。
场景是：我有两个 EditTexts。每当更改任何 EditText 的文本时，我希望另一个 EditText 在发生另一个预定义事件之前不响应用户点击。
为了实现这一点，我尝试了这个：
@Override
protected void onResume() {
super.onResume();
Log.d(TAG, "onResume");
registerBroadcastReceivers();
}
// Register BroadcastReceivers
private void registerBroadcastReceivers() {
Log.d(TAG, "Registering broadcast receivers.");
// Google response receiver
googleResponseReceiver = new GoogleAPIResponseReceiver();
IntentFilter googleResponseIntentFilter = new IntentFilter(
RS_GoogleApiIntentService.ACTION_RECEIVED_GOOGLE_RESPONSE);
googleResponseIntentFilter.addCategory(Intent.CATEGORY_DEFAULT);
LocalBroadcastManager.getInstance(this).registerReceiver(
googleResponseReceiver, googleResponseIntentFilter);
}
editText1.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
// Set EditText non-focusable
MyActivity.this.editText2.setFocusableInTouchMode(false);
}
});
.
.
.
// Somewhere in one function I call below function to start an IntentService.
.
.
.
// Call Google API with given URL
private void CallGoogleApiWithUrl(String url, int requestId) {
Intent intent = new Intent(this, RS_GoogleApiIntentService.class);
intent.putExtra(RS_GoogleApiIntentService.EXTRA_URL_STRING, url);
intent.putExtra(RS_GoogleApiIntentService.EXTRA_GOOGLE_API_REQUEST_ID,
requestId);
startService(intent);
}
// Broadcast receiver for Google API response
public class GoogleAPIResponseReceiver extends BroadcastReceiver {
// Enabling EditText works up to this point.
@Override
public void onReceive(Context context, Intent intent) {
// Stops working now onwards.
}
}
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// Set EditText focusable
MyActivity.this.editText2.setFocusableInTouchMode(true);
}

EditText 再也不会获得焦点。禁用焦点有效，但再次启用它不起作用。我也尝试过使用editText2.setEnabled();方法。它也没有用。
