Question

我希望EditText暂时不会获得赌注。

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不响应用户点击，直到发生另一个预定义事件。

为了达到这个目的，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永远不会再次获得焦点。禁用焦点工作但再次启用它不会。我也尝试使用editText2.setEnabled();方法。它也不起作用。

Answer 1

这真的很简单我的朋友。您可以尝试以下内容：

   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);
}

只需更新您的代码，然后尝试。这将是非常有效的。如果不是那么让我知道，我会帮助你。

享受编码......：）

Answer 2

Timer timer = new Timer();
timer.schedule(new TimerTask() {

  @Override
  public void run() {
    editText2.setEnable(false);
    editText2.setClickable(false);
  }
}, 20);

Answer 3

试试这个..

editText2.clearFocus();

Answer 4

如果您想要关注editText2.requestFocus();，请设置EditText。

Answer 5

将其写入活动的清单文件中，它会在第一时间通过创建活动对编辑文本进行散焦。并通过触摸编辑文本

重新获得焦点

android:windowSoftInputMode="adjustPan|stateHidden"

Answer 6

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>'

临时禁用EditText
