**在使用SmartImageView之前要先下載下傳它的源代碼,登入https://github.com/loopj/android-smart-image-view 下載下傳android-smart-image-view-1.0.0.jar然後将SmartImageView的源代碼引入到自己的項目中。
建立一個ImageViewDemo項目,把android-smart-image-view-1.0.0.jar複制到項目的libs下,一定不要忘記右擊Add as library,然後下面會出現兩個包。**
下面就需要修改代碼了,首先在activity_main.xml中添加一個SmartImageView控件:**
<com.loopj.android.image.SmartImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/siv"
/>
完整代碼為:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<ImageView
android:id="@+id/iv"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
/>
<EditText
android:id="@+id/et_path"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="請輸入圖檔路徑"
android:text="http://b.hiphotos.baidu.com/image/w%3D310/sign=8671be31b8a1cd1105b674218913c8b0/ac4bd11373f082022402cb3e49fbfbedab641b1a.jpg"
android:maxLines="1" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="click"
android:text="浏覽" />
<com.loopj.android.image.SmartImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/siv"
/>
</LinearLayout>
在MainActivity中使用SmartImageView控件的代碼如下:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_path = (EditText) findViewById(R.id.et_path);
}
public void click(View view) {
SmartImageView siv = (SmartImageViewfindViewById(R.id.siv);
siv.setImageUrl(et_path.getText().toString().trim(), R.mipmap.ic_launcher, R.mipmap.ic_launcher);
}
完整代碼為:
package cn.edu.bzu.imageviewdemo;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import com.loopj.android.image.SmartImageView;
public class MainActivity extends AppCompatActivity {
private EditText et_path;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_path = (EditText) findViewById(R.id.et_path);
}
public void click(View view) {
SmartImageView siv = (SmartImageView) findViewById(R.id.siv);
siv.setImageUrl(et_path.getText().toString().trim(), R.mipmap.ic_launcher, R.mipmap.ic_launcher);
}
}
