在android的imageView中动态设置图像

Question

我是android编程的新手。我想在显示时在一个xml中动态设置图像。具体来说，我将项目相关的图像存储在drawable文件夹中。此外，我将图像名称存储在字符串变量中，并尝试动态地将这些图像设置为imageview。但图像没有显示。

我的代码：

    protected void onCreate( Bundle savedInstanceState ) 
    {
       super.onCreate( savedInstanceState );
       setContentView( R.layout.stone );    

       imageView = ( ImageView )findViewById( R.id.stone_xxxx );

       Intent intent = getIntent();
       position = intent.getStringExtra( "POSITION" );

       if ( position == "0" )
       {
         int imageResource = getResources().getIdentifier(     "@drawable/stone_a1", null, getPackageName() );
        Drawable res = getResources().getDrawable(imageResource);
        imageView.setImageDrawable( res );
        }
    }

希望它对你有用。。

imagev1=(ImageView) findViewById(R.id.imageViewslider22);
            final int []imageArray={R.drawable.img1,R.drawable.img2,R.drawable.img3,R.drawable.img4,R.drawable.slider3,R.drawable.slider4,R.drawable.slider5,R.drawable.slider6,R.drawable.slider7};

            final Handler handler = new Handler();
            Runnable runnable = new Runnable() {
            int i=0;
            public void run() {
                        imagev1.setImageResource(imageArray[i]);
                            i++;
                                if(i>imageArray.length-1)
            {
            i=0;    
            }
            handler.postDelayed(this, 30000);  //for interval...
            }
            };
            handler.postDelayed(runnable, 2000); //for initial delay..

试试这个

final int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    imageView.setBackgroundDrawable( getResources().getDrawable(R.drawable.stone_a1) );
} else {
    imageView.setBackground( getResources().getDrawable(R.drawable.stone_a1));
}
