前言：一个比较通用型的弹出框，献丑了。
核心类AbstractDialog，这是一个虚基类，用于继承使用，当然自身也已经包含了title、content、左按钮、右按钮的等等基本UI雏形，用户只需要继承重写setLayoutView（）就可以自定义界面了，灵活的很。
源码就这几个类，很通俗易懂，可以自己手动修改成自己想要的效果，这里更多的只是提供了一个我自己码代码的写法，或者是风格吧，或只是提供一个参考。

自定义操作如下：
自定义Dialog类，继承AbstractDialog，重写setLayoutView，引入自己的layout.xml，灵活的很，根据以下代码，相信你一看就懂。
import android.support.v4.app.FragmentActivity;
import android.text.method.ScrollingMovementMethod;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.yaoxiaowen.download.sample.R;
public class MDialog extends AbstractDialog {
@Override
public View setLayoutView(final FragmentActivity activity) {
LayoutInflater inflater = activity.getLayoutInflater();
final View view = inflater.inflate(R.layout.m_dialog_layout, null);
TextView tv_dialog_title = view.findViewById(R.id.abstract_tv_dialog_title);
ImageView img_dialog_cancle = view.findViewById(R.id.img_dialog_cancle);
//中部
TextView tv_dialog_content = view.findViewById(R.id.tv_dialog_content);
tv_dialog_content.setMovementMethod(ScrollingMovementMethod.getInstance());
//底部
TextView tv_right = view.findViewById(R.id.tv_right);
TextView tv_left = view.findViewById(R.id.tv_left);
img_dialog_cancle.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(activity,"点击取消",Toast.LENGTH_LONG).show();
}
});
tv_right.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(activity,"点击右边",Toast.LENGTH_LONG).show();
}
});
tv_left.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(activity,"点击左边",Toast.LENGTH_LONG).show();
}
});
return view;
}
}
m_dialog_layout.xml
使用方法如下：
new MDialog().build(FirstActivity.this)
.setTitleVisible(false) //配置默认头部是否可见
.setContentVisible(false)//配置默认内容控件是否可见
.setLeftVisible(false)//配置默认左按钮是否可见
.setRightVisible(false)//配置默认右按钮是否可见
.setOnClickCancle(new AbstractDialog.Onclick() { //配置右上角删除按钮监听函数
@Override
public void onClick() {
Toast.makeText(FirstActivity.this,"点击取消",Toast.LENGTH_LONG).show();
}
})
.setTitle("温馨提示") //配置默认头部文字
.setLeftStr("左按钮") //配置默认左按钮文字
.setRightStr("右按钮") //配置默认右按钮文字
.show(); //弹出展示
