我想让 EditText 暂时不获取焦点。

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 在另一个预定义事件发生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);
}

布局:

EditText 再也不会获得焦点。禁用焦点有效，但再次启用它无效。我还尝试使用 editText2.setEnabled(); 方法。它也没有用。

最佳答案

这真的很简单我的 friend 。 您可以尝试以下操作:

   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);
}

只需像上面那样更新您的代码并尝试。那肯定会奏效。如果没有，请告诉我，我会帮助你。

享受编码......:)
