dialog代码，基本与普通写法一样，只是加一个回调方法
package com.cn.wq.dialog;
import android.app.Activity;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.util.Log;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.EditText;
import android.widget.TextView;
import com.cn.wq.dialog.view.ResizeLayout;
/**

public class DialogInputUtils {
private static DialogInputUtils instance;
private AlertDialog dialog;
private EditText mEditText;
private TextView mTvSend;
private boolean isShowInput = false;
private OnTalkClickListener onTalkClick;
private DialogInputUtils() {
}
public static DialogInputUtils getInstance() {
if (instance == null) {
synchronized (DialogInputUtils.class) {
if (instance == null) {
instance = new DialogInputUtils();
}
}
}
return instance;
}
public void setOnTalkClick(OnTalkClickListener onTalkClick) {
this.onTalkClick = onTalkClick;
}
public interface OnTalkClickListener {
void onTalkClick(String content);
}
/**

*/
public void showInputDialog(final Activity activity) {
AlertDialog.Builder builder = new AlertDialog.Builder(activity, R.style.Dialog_Fullscreen);
final View view = LayoutInflater.from(activity).inflate(R.layout.dialog_edittext, null);
builder.setView(view);
builder.setCancelable(true);
dialog = builder.create();
dialog.setCanceledOnTouchOutside(true);

private void setDialog(final Activity activity) {

lp.x = 0;
lp.y = 0;
lp.width = WindowManager.LayoutParams.MATCH_PARENT;
final int height = (int) activity.getResources().getDimension(R.dimen.parent_list_height);
lp.height = height;
dialog.getWindow().setAttributes(lp);
mEditText = (EditText) dialog.getWindow().findViewById(R.id.edt_text);

if (DialogInputUtils.this.onTalkClick != null) {

}
private void addListener(View view) {
final ResizeLayout rootLayout = (ResizeLayout) view.findViewById(R.id.resize_layout);

2 resizeLayout 内容，由于需要监听dialog的关闭与打开，系统提供的方法很不管用，只能通过自定义方式实现，在这里我是通过dialog打开与关闭时的坐标变化，来判断dialog是打开还是关闭状态
package com.cn.wq.dialog.view;
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.EditText;
import android.widget.LinearLayout;
import com.cn.wq.dialog.R;
public class ResizeLayout extends LinearLayout {
private static int count = 0;
private final int keyHeight;
private EditText editText;
private int[] position = new int[2];
private final int screenHeight;
public ResizeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
screenHeight = ScreenUtils.getScreenHeight(context);
keyHeight = screenHeight / 3;
Log.w("input", "screenHeight:" + screenHeight);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
if (editText == null) {
editText = (EditText) this.findViewById(R.id.edt_text);
}
if (editText != null) {
editText.getLocationOnScreen(position);
Log.w("input", "\t position on screenY:" + position[1]);
if (listener != null)
listener.onSoftKeyboardShown(position[1] < screenHeight * 0.7);
}
}
public interface Listener {
public void onSoftKeyboardShown(boolean isShowing);
}
private Listener listener;
public void setListener(Listener listener) {
this.listener = listener;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
3 layout比较简单
