ToastModule.javaを変更した後にネイティブの反応を再現する方法

Question

最近ToastAndroidを反応させるためにスタイリングを追加したいと思ってToastModule.javaファイルを編集しましたが、 、ネイティブToastModuleを再構築しない、

編集コード

package com.facebook.react.modules.toast; 

import android.view.Gravity; 
import android.widget.Toast; 
import android.widget.LinearLayout; 
import android.widget.TextView; 
import android.graphics.Color; 

import com.facebook.react.bridge.NativeModule; 
import com.facebook.react.bridge.ReactApplicationContext; 
import com.facebook.react.bridge.ReactContextBaseJavaModule; 
import com.facebook.react.bridge.ReactMethod; 
import com.facebook.react.common.MapBuilder; 
import com.facebook.react.bridge.UiThreadUtil; 

import java.util.Map; 

/** 
* {@link NativeModule} that allows JS to show an Android Toast. 
*/ 
public class ToastModule extends ReactContextBaseJavaModule { 

    private static final String DURATION_SHORT_KEY = "SHORT"; 
    private static final String DURATION_LONG_KEY = "LONG"; 

    private static final String GRAVITY_TOP_KEY = "TOP"; 
    private static final String GRAVITY_BOTTOM_KEY = "BOTTOM"; 
    private static final String GRAVITY_CENTER = "CENTER"; 

    public ToastModule(ReactApplicationContext reactContext) { 
    super(reactContext); 
    } 

    @Override 
    public String getName() { 
    return "ToastAndroid"; 
    } 

    @Override 
    public Map<String, Object> getConstants() { 
    final Map<String, Object> constants = MapBuilder.newHashMap(); 
    constants.put(DURATION_SHORT_KEY, Toast.LENGTH_SHORT); 
    constants.put(DURATION_LONG_KEY, Toast.LENGTH_LONG); 
    constants.put(GRAVITY_TOP_KEY, Gravity.TOP | Gravity.CENTER_HORIZONTAL); 
    constants.put(GRAVITY_BOTTOM_KEY, Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL); 
    constants.put(GRAVITY_CENTER, Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL); 
    return constants; 
    } 

    @ReactMethod 
    public void show(final String message, final int duration) { 
    UiThreadUtil.runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
     Toast.makeText(getReactApplicationContext(), message, duration).show(); 
     } 
    }); 
    } 

    @ReactMethod 
    public void showWithGravity(final String message, final int duration, final int gravity) { 
    UiThreadUtil.runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
     Toast toast = Toast.makeText(getReactApplicationContext()); 

     LinearLayout layout = new LinearLayout(getReactApplicationContext()); 

     layout.setBackgroundColor(Color.parseColor("#FFFFFF")); 

     TextView tv = new TextView(this); 

     tv.setTextColor(Color.RED); 
     tv.setTextSize(14); 
     tv.setGravity(Gravity.CENTER_VERTICAL); 
     tv.setText(message); 

     layout.addView(tv); 

     toast.setView(layout); 
     toast.setDuration(duration); 
     toast.setGravity(gravity, 0, 0); 
     toast.show(); 
     } 
    }); 
    } 
}

に私は本当に私のプロジェクトのためにこれを必要とする原料溶液を助けてください：

public void showToast(String mex) { 

    Toast toast = Toast.makeText(this, mex, Toast.LENGTH_SHORT); 
    toast.getView().setBackgroundResource(R.drawable.bg_primary_radius); 
    toast.getView().findViewById(android.R.id.message).setBackgroundColor(primaryColor); 

    // make your other customization 

    toast.show(); 
} 

：このようなクラスにメソッドを置きます
