Alertdialog和ButterKnife上的IllegalStateException

我是新的在android上，我想在我的代碼上使用butterknife。在我的實踐，我有在主活動佈局的FAB按鈕：Alertdialog和ButterKnife上的IllegalStateException

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/btn_fab" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom|end" 
    android:layout_margin="10dp" 
    android:onClick="addURL" 
    android:src="@android:drawable/ic_input_add" 
    app:fabSize="normal" />

點擊我的FAB之後，alertDialog的出現。有在對話框的自定義佈局的文本編輯觀點：

<EditText 
    android:id="@+id/editText_add_url" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" />

這是我的onclick：

public void addURL(View view) { 

    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    builder.setTitle("Add your URL:"); 
    ButterKnife.setDebug(true); 
    ButterKnife.bind(this, view); 
    builder.setPositiveButton("Add", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 

      addURLToList(); 
     } 
    });

和：

private void addURLToList() { 
    editTextAddURL.setText("Hi"); 

}

我得到editText_add_url參考像場：

public class MainActivity extends AppCompatActivity { 

@BindView(R.id.editText_add_url) 
EditText editTextAddURL;

運行我得到這個錯誤後：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.manifest.simplefiledownloadmanager/com.example.manifest.simplefiledownloadmanager.MainActivity}: java.lang.IllegalStateException: Required view 'editText_add_url' with ID 2131558531 for field 'editTextAddURL' was not found.

我知道我的錯誤是因爲butterKnife減速，但我不知道怎麼用使用自定義佈局的alertdialog上的Butterknife。謝謝你們。

編輯------------ 這是我的onCreate方法：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    ButterKnife.bind(this); 
    initView(); 
} 
    private void initView() { 
    //set Toolbar to Activity 
    setSupportActionBar(toolbar); 

    //set Fragment 
    getSupportFragmentManager().beginTransaction().add(R.id.frameLayout_container, 
      new ListDownloadFragment()).commit(); 


} 

public void addURL(View view) { 

    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    builder.setTitle("Add your URL:"); 
    ButterKnife.setDebug(true); 
    ButterKnife.bind(MainActivity.this, view); 
    builder.setPositiveButton("Add", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 

      addURLToList(); 
     } 
    }); 

    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int which) { 
      dialog.dismiss(); 

     } 
    }); 

    View inflate = getLayoutInflater().inflate(R.layout.dialog_add_url, null); 
    builder.setView(inflate); 
    dialog = builder.show(); 
} 

private void addURLToList() { 
    editTextAddURL.setText("Hi"); 

}

你在哪裏誇大了你的觀點？ –

請發佈您的onCreate方法，因爲崩潰發生在那裏 –

從你調用「addURL」方法？ –

當調用ButterKnife.bind（）中的onCreate（）ButterKnife試圖綁定註釋所有@BindView來自當前佈局的視圖。但是，R.layout.activity_main不包含ID爲R.id.editText_add_url的視圖。因此它崩潰。

我通常建議只使用ButterKnife作爲類的主視圖並調用findViewById來查找對話框的視圖等。

您可以使用私有類來綁定片段中對話框佈局的視圖，就像這樣。

//To bind with the dialog view using butterKnife 
public class DialogViewHolder { 

    @BindView(R.id.editText_add_url) 
    EditText editTextAddURL; 

    DialogViewHolder(View view) { 
     ButterKnife.bind(this, view); 
    } 
} 
public DialogViewHolder dialogViewHolder;

然後在addUrl功能，您可以使用它像，

View inflate = View.inflate(getContext(), R.layout.dialog_add_url, null); 
dialogViewHolder = new DialogViewHolder(inflate);

它應該做的伎倆。
