Android自定义dialog弹出布局

定义一个弹窗布局

首先定义一个dailog_set_password.xml布局文件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#66ff6600"
        android:gravity="center"
        android:padding="10dp"
        android:text="设置密码"
        android:textColor="@color/black"
        android:textSize="20sp" />

    <EditText
        android:id="@+id/et_password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请输入密码"
        android:inputType="textPassword" >
    </EditText>

    <EditText
        android:id="@+id/et_password_confirm"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="请再次输入密码"
        android:inputType="textPassword" >
    </EditText>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <Button
            android:id="@+id/btn_ok"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="确定" />

        <Button
            android:id="@+id/btn_cancel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="取消" />
    </LinearLayout>

</LinearLayout>

显示这个布局文件

private void showPasswordSetDailog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        final AlertDialog dialog = builder.create();

        View view = View.inflate(this, R.layout.dailog_set_password, null);
        // dialog.setView(view);// 将自定义的布局文件设置给dialog
        dialog.setView(view, 0, 0, 0, 0);// 设置边距为0,保证在2.x的版本上运行没问题

        final EditText etPassword = (EditText) view
                .findViewById(R.id.et_password);
        final EditText etPasswordConfirm = (EditText) view
                .findViewById(R.id.et_password_confirm);

        Button btnOK = (Button) view.findViewById(R.id.btn_ok);
        Button btnCancel = (Button) view.findViewById(R.id.btn_cancel);

        btnOK.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                String password = etPassword.getText().toString();
                String passwordConfirm = etPasswordConfirm.getText().toString();
                // password!=null && !password.equals("")
                if (!TextUtils.isEmpty(password) && !passwordConfirm.isEmpty()) {
                    if (password.equals(passwordConfirm)) {
                        // Toast.makeText(HomeActivity.this, "登录成功!",
                        // Toast.LENGTH_SHORT).show();

                        // 将密码保存起来
                        mPref.edit()
                                .putString("password",
                                        MD5Utils.encode(password)).commit();

                        dialog.dismiss();

                        // 跳转到手机防盗页
                        startActivity(new Intent(HomeActivity.this,
                                LostFindActivity.class));
                    } else {
                        Toast.makeText(HomeActivity.this, "两次密码不一致!",
                                Toast.LENGTH_SHORT).show();
                    }
                } else {
                    Toast.makeText(HomeActivity.this, "输入框内容不能为空!",
                            Toast.LENGTH_SHORT).show();
                }
            }
        });

        btnCancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                dialog.dismiss();// 隐藏dialog
            }
        });

        dialog.show();
    }
