我正在研究網(wǎng)格視圖,我是android的新手.我之前在gridview中遇到了一個(gè)問(wèn)題,我解決了自己發(fā)布鏈接,因?yàn)榇a與上下文任務(wù)中添加的新功能相同

i dont know how to get the position of the img that i click so i can pass it to next acitvity

剩下的代碼如下

@Override

public boolean onContextItemSelected(MenuItem item) {

if(item.getTitle()=="View"){function1(item.getItemId());}

else if(item.getTitle()=="Details"){function2(item.getItemId());}

else if(item.getTitle()=="Delete"){function3(item.getItemId());}

else {return false;}

return true;

}

public void function1(int id){

//String prompt;

// Sending image id to FullScreenActivity

/*Toast.makeText(getApplicationContext(),

path,

Toast.LENGTH_LONG).show();*/

Intent i = new Intent(getApplicationContext(), FullImageActivity.class);

i.putExtra("id", path );

startActivity(i);

}

public void function2(int id){

Toast.makeText(this, "Details func called", Toast.LENGTH_SHORT).show();

}

public void function3(int id){

File file = new File(path);

if(file.exists())

{

boolean deleted = file.delete();

}

myImageAdapter.notifyDataSetChanged();

//adapter.notifyDataSetChanged();

//gv.invalidateViews();

Toast.makeText(this, "function delete called", Toast.LENGTH_SHORT).show();

}

我不允許發(fā)布圖像,因?yàn)槲业穆曌u(yù)較少但是當(dāng)調(diào)用刪除功能時(shí),圖像被刪除但網(wǎng)格視圖中有一個(gè)空白空間我希望在調(diào)用刪除功能后自動(dòng)填充空白空間.

總結(jié)
