临时禁用EditText

我希望EditText暂时不获得犯规。

场景是：我有两个EditText。每当任何EditText的文本发生更改时，我都希望另一个EditText在发生另一个预定义事件之前不对用户单击做出响应。

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);
}

布局：

EditText再也无法获得焦点。禁用焦点有效，但再次启用则无效。我还尝试了使用editText2.setEnabled();方法。它也不起作用。

这真的很简单，我的朋友。你可以试试下面的东西：

   editText1.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before,
                int count) {
        // Set EditText non-focusable
        editText2.setEnable(false);
        editText2.setClickable(false);

    }
});
.
.  // some work
.
listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
        // Set EditText focusable
                editText2.setEnable(true);
        editText2.setClickable(true);
}

只需像上面一样更新您的代码，然后尝试。那会奏效的。如果不告诉我，我会帮你的。

享受编码…：）

Timer timer = new Timer();
timer.schedule(new TimerTask() {
  @Override
  public void run() {
    editText2.setEnable(false);
    editText2.setClickable(false);
  }
}, 20);

试试这个。。

editText2.clearFocus();

当您想专注于EditText时，可以设置editText2.requestFocus();。

将其写入活动的清单文件中，它第一次通过创建活动来散焦edittext。并通过触摸编辑文本重新获得焦点

android:windowSoftInputMode="adjustPan|stateHidden"

您可以使用以下代码并通过java进行相应的操作。

`<EditText ...
    android:clickable="false" 
    android:cursorVisible="false" 
    android:focusable="false" 
    android:focusableInTouchMode="false">
 </EditText>'
