使GridView具有多個佈局

我想在我的gridView中設置一個對象：名爲artefact的對象可以是圖像或消息，但是在運行我的代碼並添加一個對象後，網格視圖不會出現。這是我的代碼。 THISIS我的適配器使GridView具有多個佈局

public ArtifactAdapter(Context context,List<Artifact> artifacts) 
{ 
    this.context =context; 
    this.artifacts = artifacts; 
} 
@Override 
public int getCount() { 

    // Number of times getView method call depends upon gridValues.length 
    return artifacts.size(); 
} 

@Override 
public Object getItem(int position) { 

    return null; 
} 

@Override 
public long getItemId(int position) { 

    return 0; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 

    // LayoutInflator to call external grid_item.xml file 


    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    Artifact artifact = artifacts.get(position); 
    View gridView; 
    gridView = new View(context); 
    if (convertView == null) { 

     ; 
     switch (artifact.getType()) { 
      case 1: 

       gridView = inflater.inflate(R.layout.artifact_article, null); 
       mTitle = (TextView) gridView.findViewById(R.id.titre); 
       mPseudo = (TextView) gridView.findViewById(R.id.pseudo); 
       mMessage = (TextView) gridView.findViewById(R.id.message_input); 
       mTitle.setText(artifact.getTitle()); 
       mPseudo.setText(artifact.getPseudo()); 
       mMessage.setText(artifact.getMessage()); 


      case 2: 
       gridView = inflater.inflate(R.layout.artifact_image, null); 
       mPseudo = (TextView) gridView.findViewById(R.id.pseudo); 
       mImage = (ImageView) gridView.findViewById(R.id.imageReceived); 
       mPseudo.setText(artifact.getPseudo()); 
       mImage.setImageBitmap(BitmapFactory.decodeFile(artifact.getImagePath())); 


     } 
    } 
    else { 

      gridView = (View) convertView; 
     } 
    return gridView; 
    } 


}

這個活動

GridView listArtifactView; 
    List<Artifact> listArtifact = new ArrayList<>(); 
    ArtifactAdapter artifactAdapter = new ArtifactAdapter(this,listArtifact); 
Artifact artefact = new Artifact(getPseudo()); 
        artefact.setTitle(titre.getText().toString()); 
        artefact.setMessage(message.getText().toString()); 
        artefact.setType(1); 

listArtifactView = (GridView) findViewById(R.id.listArtifactView); 

     listArtifactView.setAdapter(artifactAdapter); 

       listArtifact.add(artefact);

我不知道你想在這裏實現。但是您getView改變這樣的事情是什麼。

LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    Artifact artifact = artifacts.get(position); 
    if (convertView == null) { 

     switch (artifact.getType()) { 
      case 1: 

       convertView = inflater.inflate(R.layout.artifact_article, null); 
       mTitle = (TextView) convertView .findViewById(R.id.titre); 
       mPseudo = (TextView) convertView .findViewById(R.id.pseudo); 
       mMessage = (TextView) convertView .findViewById(R.id.message_input); 
       mTitle.setText(artifact.getTitle()); 
       mPseudo.setText(artifact.getPseudo()); 
       mMessage.setText(artifact.getMessage()); 


      case 2: 
       convertView = inflater.inflate(R.layout.artifact_image, null); 
       mPseudo = (TextView) convertView .findViewById(R.id.pseudo); 
       mImage = (ImageView) convertView .findViewById(R.id.imageReceived); 
       mPseudo.setText(artifact.getPseudo()); 
       mImage.setImageBitmap(BitmapFactory.decodeFile(artifact.getImagePath())); 


     } 
    } 

    return convertView

看看是否有幫助。
