当android报这个错误:
Caused by: android.content.res.Resources$NotFoundException: File res/drawable/abc_ic_ab_back_material.xml from drawable resource ID
Android invalid drawable tag vector
一直都没找到什么好的解决方法,最后是修改appcompat-v7依赖包
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
//compile 'com.android.support:appcompat-v7:24.0.1-beta1'
//noinspection GradleCompatible
compile 'com.android.support:appcompat-v7:23.0.1'
}
从24.0.1改成23.0.1问题解决了.
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'
compile 'com.android.support:design:23.2.1'
}
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new Thread(new Runnable() {
@Override
public void run() {
try {
URL url = new URL(“http://192.168.1.205/verify.php?rand=29569″);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();//建立链接
InputStream in = conn.getInputStream();//读取图片先
bitmap = BitmapFactory.decodeStream(in);//解码图片
handler.sendEmptyMessage(1);//发送消息,把图片显示出去
