Android：根據edittext選項顯示圖像的Imageview

Question

我的res/drawable文件夾中有10個動物圖像，我想根據編輯文本選項逐個顯示圖像。我的意思是在編輯文本中，當我們輸入體重時，根據體重的範圍（如果體重在60-70之間，圖像視圖顯示老虎）對於每個體重圖像視圖顯示具有不同聲音的不同動物（根據範圍）。由於我是Android新手，無法解決這個問題，我們如何實現這一點？任何想法？

幫助總是讚賞....！

Answer 1

根據你EDITTEXT值可以傳遞值以下功能

private void displayImg(int value){ 
    ImageView im = (ImageView)findViewById(R.id.img1); 
    if (value >= 0 && value < 10){ 
     im.setBackgroundResource(R.drawable.animal1); 
    }else if (value >=10 && value <20){ 
     im.setBackgroundResource(R.drawable.animal2); 
    } 
      ..... so on... 
} 

Answer 2

ImageView imgAnimal = (ImageView)findViewById(R.id.image_animal); 
EditText editWeight = (EditText)findViewById(R.id.edit_weight); 
try { 
    // get the weight, will throw an exception if 
    // the EditText doesn't contain a valid integer 
    int weight = Integer.parseInt(editWeight.getText().toString()); 
    // if you reach this, the conversion was successful, but you might want to 
    // check for negative values, or values too small/too big and warn the user 
    // if you want to change the image based on a range, 
    // the only way is to use chained if's 
    if (weight >= 60 && weight <= 70) 
     imgAnimal.setImageResource(R.drawable.tiger); 
    else if (weight > 70 && weight <= 80) 
     imgAnimal.setImageResource(R.drawable.some_animal); 
    // and so on... 
} catch (NumberFormatException nfe) { 
    // the EditText does not contain a number, warn the user or something 
}
